Choosing RAL palette colors in powder coating – a technical guide

Powder coating makes it possible to achieve durable decorative and protective coatings  on metal surfaces, and selecting the right color from the RAL palette is crucial to the  final result. The RAL palette is a standardized set of colors that simplifies project  communication between customers, designers, and contractors. Thanks to this, when  ordering powder paints with a specific RAL code, we can be confident in color  consistency regardless of the paint manufacturer or batch. In this article, we explain  what the RAL palette is and why it matters in industrial coating, and how the color  choice affects the coating’s technical parameters (UV resistance, thickness, durability,  pigment properties). We also describe available surface finishes (matt, gloss, texture,  metallic) and suggest which colors are most commonly used in the construction,  automotive, and furniture industries. Finally, we present the offer of ABC Colorex—our  wide range of RAL colors, customer samples, and an invitation to get in touch.

RAL palette – color standard in powder coating 

The RAL palette is an international color identification standard used for decades across  Europe in industry and design. The system was created in Germany back in 1927 to  standardize color naming and facilitate communication between manufacturer and  customer. The classic RAL palette (RAL Classic) currently includes 216 colors identified  by four-digit codes with the “RAL” prefix (e.g., RAL 9010 is pure white). The first digit  indicates the color group (1xxx – yellows, 2xxx – oranges, 3xxx – reds and pinks, 4xxx – violets, 5xxx – blues, 6xxx – greens, 7xxx – greys, 8xxx – browns, 9xxx – whites and  blacks). Thanks to this system, each color has a unique number and name, eliminating  mistakes—rather than describing a color in words, it’s enough to give the RAL code and  both parties know exactly which shade is meant. The RAL palette has become a  foundation for powder paint producers—virtually all suppliers offer their paints in  shades compliant with RAL Classic. There are also expanded systems like RAL Design  (1,825 colors for creative applications) and RAL Effect (490 colors, including metallics),  but in powder coating the RAL Classic palette predominates as the main color language.

In project communication the RAL palette plays a huge role. It enables precise color  agreements at the planning stage; e.g., an architect can specify that aluminium façade  elements are to be powder-coated in RAL 7016 (anthracite), and the window  manufacturer will deliver the product in exactly that color. RAL standardization  simplifies ordering and quality control—the purchasing department orders RAL powder  paints by number, the coating shop applies the finish, and the investor accepts the  elements in the expected shade. The RAL palette is therefore a shared point of reference  that ensures the aesthetic coherence of the entire project. Note that the RAL Institute  provides color standards separately for different gloss levels; for every color there is a  gloss and a matt sample, since gloss level affects the visual perception of color. Good  practice requires that when choosing a color you also explicitly define the finish (e.g.,  RAL 9010 matt vs. RAL 9010 gloss) to ensure the resulting RAL powder coating meets  aesthetic expectations. 

The impact of RAL color on the technical parameters of a powder coating Choosing a color from the RAL palette is not only an aesthetic decision—the hue (more  precisely, the pigments used to achieve it) can influence certain technical parameters of  a powder coating. Below we discuss the key aspects: UV resistance, the required  coating thickness (related to hiding power), overall durability of the coating, and specific  pigment properties. 

UV resistance and color durability 

One important factor is a color’s resistance to ultraviolet (UV) radiation and the related  long-term color stability. Organic pigments used to obtain bright, vivid colors (e.g., light  reds, oranges, yellows) generally have lower UV stability and can fade over time in  sunlight. In contrast, inorganic pigments (e.g., iron oxides for reds and browns,  chromium oxide for greens, titanium dioxide for whites) provide better UV resistance and  color fastness, though the palette with them tends to be less flashy. In practice, dark  and subdued shades based on stable pigments (graphite greys, blacks, navy blues) are  less prone to sun fading, while light, pastel shades may show visual changes more  quickly with prolonged sun exposure (e.g., slight fading, loss of intensity). For exterior  projects where maximum color durability is required, it’s better to choose façade  (architectural) powder paints with UV-resistant pigments and polyester resin. Special  so-called super-durable powder paints are available for outdoor use; even intense  colors (e.g., red RAL 3020) can better resist fading thanks to improved pigment  chemistry and stabilizing additives. In general, when planning colors for weather exposed elements, check with the paint supplier that the chosen shade has good UV  resistance, or consider an additional clear topcoat (with UV filter) to protect the color.  This helps the protective coating retain its decorative qualities for many years. 

Coating thickness vs. color hiding power 

Color also affects practical application aspects, such as the required powder layer 

thickness to achieve full coverage. Different pigments have different tinting strengths  and optical hiding power. For example, yellow and light red powder shades typically have  poorer hiding power than dark colors. This is because many bright pigments (e.g.,  organic azo pigments for reds and yellows) are inherently semi-transparent. To cover a  dark substrate with such a color, a thicker layer is needed or a primer must be used. In  coating practice this means that when powder-coating a part in an intense yellow or  orange RAL shade, you should ensure adequate film thickness (typically 80–120 µm  instead of a ~60 µm minimum) or apply a white undercoat to boost final coverage.  Conversely, dark colors (black, navy, brown) and those with a lot of titanium dioxide  (whites) cover much better—often a thinner film suffices for a uniform color, which can  save material. Remember, however, that every powder paint has a recommended  thickness range for optimal properties—these values should not be excessively  exceeded to avoid defects (e.g., slumping before cure or reduced mechanical resistance  of overly thick films). In short, color choice can influence the application technique— light colors often require more attention to achieve full hiding, whereas dark colors  make it easier to obtain a fully covering film. 

Pigment properties vs. coating durability and strength 

Pigments used to impart color can also indirectly affect the mechanical and chemical  durability of a powder coating. Metallic pigments (aluminium flakes in metallic shades),  for example, add a visual effect but can slightly reduce corrosion resistance if the paint  is not properly formulated. Hence, for metallic-effect powder paints a clear coat is often  recommended as a sealer—it improves resistance to metallic-pigment oxidation and  enhances gloss retention. In general, reputable manufacturers formulate decorative  powder paints so that protective properties are maintained regardless of color. In  practice, each RAL color is available in different quality classes; for example, a polyester  powder paint in the Qualicoat Class 1 standard meets basic exterior requirements  (approx. 5–10 years of color durability), while the same shade in Class 2 (super-durable)  offers longer durability (>15 years) thanks to more robust pigments and resins. When  choosing a color, ask about the available quality variants of the powder paint in that  shade. In addition, some exceptionally light and clean colors may contain a higher  pigment fraction at the expense of resin content, which can slightly affect mechanical  properties (e.g., hardness or flexibility of the film). From an end user’s perspective,  however, these differences are minor—most RAL powder coatings, when properly  applied, exhibit excellent adhesion, impact and scratch resistance, and effective  corrosion protection of the substrate, regardless of the selected color. To sum up, the  coating color may call for certain process adjustments (film thickness, protective clear  coat), but the final coating—if chosen for the exposure conditions—will fulfill both  decorative and protective functions. 

Types of powder finishes: matt, gloss, texture, metallic 

For every RAL color there are different surface-finish versions. The same shade can look 

different depending on gloss level or surface texture. Below are the most common  powder-coating finishes and what they mean in industrial practice. 

Gloss vs. matt 

Gloss level strongly influences how a color is perceived. A glossy surface reflects a lot of  light—colors appear more saturated and “lively”, but minor defects, scratches, and  fingerprints are also more visible. A matt surface diffuses light, giving a subdued, elegant  effect; the same shade in matt may appear slightly paler or more pastel compared to its  gloss version. Matt has the advantage of masking minor substrate imperfections better  and producing fewer reflections (desirable on large façades to avoid a mirror effect). The  choice between matt and gloss depends on the project’s aesthetic requirements—e.g.,  in furniture, matt black finishes are on trend (modern look), while in automotive, semi gloss or gloss finishes are common and easier to keep clean. Note that the RAL Institute  supplies separate color standards for different gloss levels, ensuring color matching in  both variants. Intermediate options such as semi-matt or satin (approx. 30–60% gloss)  are also available and combine features of both extremes. 

Fine texture 

This finish is not completely smooth; the surface has a delicate, grainy texture,  perceptible to the touch and visible against the light. Fine-texture powder paints contain  special additives (e.g., waxes) that produce a subtle texture during curing. Texture offers  several advantages. First, it excellently hides minor substrate defects—small scratches,  porosity, or sheet waviness become invisible under a grainy finish. Second, it’s practical:  fingerprints, dust, and small service scratches are less noticeable on a textured surface.  Finally, textured coatings are considered very durable and resistant—a film with locally  varying thickness (micro “peaks and valleys”) can better mask any future damage. No  wonder fine textures are popular in many industrial and commercial sectors, providing  an aesthetic finish with high coating durability. Typical applications include computer  enclosures, control cabinets, machine parts, and metal furniture—wherever a visual  effect paired with functionality is desired. Fine texture is often combined with different  gloss levels (e.g., black matt fine texture is very popular for fences and landscape architecture elements). 

Metallic and special effects 

Besides smooth standard colors, powder coating allows special effects by adding  suitable pigments. The most common are metallic colors—the paint contains fine metal  particles (aluminium) or mica coated with oxides, giving a shiny, shimmering look.  Examples include silver metallic shades (e.g., RAL 9006 and RAL 9007 in the RAL Classic  palette are metallic colors) and graphite metallic, often used on aluminium wheels. A  metallic-effect powder coating gives products a more premium, attractive appearance,  hence its popularity in automotive (wheels, accessories, body components), home  appliances, and furniture (handles, table legs). Keep in mind that applying metallics can 

require more skill (uniform application is important to avoid “clouding” or gloss  variations). A clear topcoat is often added to achieve an ideally smooth surface. Beyond  metallics, other effects are available: antique, chameleon, fluorescent, pearlescent, transparent, etc., allowing the RAL palette to be extended with creative finishes. In  industrial practice, special effects are used sparingly where justified by product design.  Most often, however, industry opts for classic finishes (matt/gloss, optionally texture) in  standard RAL colors, ensuring repeatability, availability, and ease of repair or touch-up. 

The most popular RAL colors in construction, automotive, and furniture Example of using RAL powder coating in automotive – wheels and bodywork in an  intense color. 

Different industry sectors prefer different selections from the RAL chart, reflecting their  specifics and aesthetic trends. Below are the most frequently chosen RAL colors in  three key sectors: construction (architecture), automotive, and furniture. These colors  are favored for their universality, practical benefits, or prevailing fashions. 

Construction (architecture and structures) 

• RAL 7016 – Anthracite grey: The absolute hit in architecture in recent years. A dark,  graphite grey used for windows, doors, aluminium façade frames, and fences. It has  become the preferred color for modern façades—for example, contemporary doors and  windows are often ordered in anthracite. Beyond aesthetics, it’s practical—dirt shows  less and it pairs well with glass, concrete, and brick. 
• RAL 9010 – Pure white (creamy white): A classic warm white used in construction for  years. Popular for door and window joinery, façades, balustrades, and finishing  elements. Although called “pure white,” it actually has a slightly broken, creamy tone,  giving a pleasant character. Often used indoors (e.g., radiators, light fittings) and on  traditional building façades. 
• RAL 9005 – Jet black (deep black): An intense black with strong depth. In construction  it’s used for modern fences, balustrades, technical enclosures, and as a contrasting  accent (e.g., black window frames in lofts). It’s a neutral, elegant color that highlights  other materials. Due to its universal nature, RAL 9005 is also frequently chosen for steel  structures and infrastructure elements. 
• RAL 9006 / RAL 9007 – White aluminium and Grey aluminium: Metallic silver shades  often used on façade panels, sills, aluminium profiles, and sheet-metal roofing. RAL  9006 (White aluminium) is a light silvery color, while RAL 9007 (Grey aluminium) is a  slightly darker graphite silver. Both provide a metallic effect that pairs well with glass and  concrete, which is why architects like them for modern building designs. • RAL 8017 – Chocolate brown: A traditional dark brown, very popular in earlier years for  window and door joinery, garage doors, gutters, and soffits. Still common in residential  and industrial construction (e.g., hall claddings). RAL 8017 is valued for neutrality and  practicality (dirt and dust are less visible), though in modern architecture it is gradually  giving way to anthracite and black.

Automotive (vehicles and transport equipment) 

• RAL 9005 – Deep black: Again at the top—fundamental in automotive. Gloss RAL 9005  is often used on car bodies (special editions, tuning) as well as wheels, chassis  components, roof rails, etc. It’s one of the most popular car colors also because it suits every brand and style. In powder coating, black is used for motorcycle frames,  suspension parts, off-road steel bumpers, and more. 
• RAL 3020 – Signal red: An intense, vivid red common on special-purpose vehicles (fire  service, rescue) and for sporty accents. RAL 3020 is used on brake calipers, tuning parts,  and in racing (roll cages, wheels)—its strong hue emphasizes dynamism. It demands  high UV resistance, but good powder paints keep even such a bold color vibrant for a  long time. 
• RAL 9006 / RAL 9007 – Silver metallic: Metallic silver shades are extremely popular in  automotive. RAL 9006 (White aluminium) and RAL 9007 (Grey aluminium) are classic  colors for alloy wheels, roof racks, mirror housings, and body trim. They deliver a metal  sheen and hide light dirt well, which is why silver has been among the most-chosen car  colors for years. Coating shops also paint accessories and motorcycle parts in these  shades. 
• RAL 6005 – Moss green: A deep green frequently used on agricultural equipment,  construction machinery, and utility vehicles. Tractors, municipal mowers, and forestry  trailers are often painted in a shade close to RAL 6005. The color hides dirt well (e.g.,  mud, grass) and blends with natural surroundings. Military vehicles use other RAL  greens and beiges (e.g., RAL 6031 matt NATO green); RAL standardization also enables  compliance with camouflage norms. 
• RAL 2004 – Pure orange: A bright orange often used on warning and construction  vehicles (e.g., excavator frames, cranes, road-service equipment). The color ensures  excellent visibility and safety, hence its presence on cones, barriers, and slow-moving  vehicles. In RAL, the 20xx group covers oranges—e.g., RAL 2004 or the even brighter RAL  2005 luminous orange. Powder coating of this kind of equipment provides a durable  protective finish that not only looks good but also shields metal from corrosion in harsh  service conditions. 

Furniture (metal furniture and fittings) 

• RAL 9016 – Signal white (cool white): A bright, clean white often chosen for office  furniture, metal shelving, chairs, lamps, etc. RAL 9016 is cooler and “whiter” than RAL  9010, giving a very modern, clean look (often called snow white). In furniture and interiors, white is timeless—fits any environment and visually enlarges spaces. Powder  paints in this shade deliver smooth, easy-to-clean surfaces, popular on metal frames,  medical cabinet fronts, and appliances. 
• RAL 9005 – Matt black: Matt black has become very fashionable in loft and industrial  furniture. Metal table frames, shelving, lamps, handles, and AV cabinets are often  powder-coated in low-gloss black. It gives an elegant, modern effect and pairs well with 

wood, glass, and concrete in loft interiors. Black RAL is also widely used in outdoor  furniture (e.g., aluminium profiles in gazebos and pergolas)—neutral and practical. • RAL 7015 – Slate grey: A subdued, medium grey with a warm, slightly bluish cast. One  of the most popular modern colors in furniture and interior design, used in both  industrial and home applications. It appears on furniture structures, equipment  enclosures, and even decorative details. As a neutral yet less obvious choice than black  or white, it adds character without dominating. 

• RAL 6021 – Pastel green (pale green): A delicate, muted green, also called sage. In  recent years it has become very popular as a color accent in designer and retro  furniture. Used, for example, for powder-coating chairs, retro fridges, and vintage-style  decorative elements. RAL 6021 is considered highly on-trend in contemporary  arrangements and can breathe new life into an old piece. Combined with gold accents, it  appears in the glamour segment. Thanks to powder coating, you get an intense, durable  pastel tone that’s scratch-resistant—important because light matt paints could  otherwise soil easily, while a powder film allows easy cleaning. 

Of course, the above are only some of the most popular colors. The full RAL palette  offers hundreds of shades that can be tailored to project requirements. In every industry  there are classic, proven colors (often defined for years by sector standards, e.g., RAL  1023 yellow for warning signs, RAL 6011 green for machinery, etc.) as well as evolving  color trends. What matters is that powder-coating aluminium and steel in standard RAL  colors guarantees repeatability—order the same color today and in a few years and you  will get the same shade, which is crucial when expanding facilities or replacing  components.
