RAL digital colour library
RAL colour families for machined parts — how each one behaves on anodised aluminium and powder coating, and where the official swatch comes from.
RAL digital colour library · See RAL licensing
Official digital RAL colour values require the applicable licence, so this table describes the colour families and how they behave instead of publishing swatches.
| RAL colour range | Finish variants | Typical use | Anodised match | Powder-coat match | Where to verify | Digitising note |
|---|---|---|---|---|---|---|
| RAL 1000 – 1999 | Matt, satin and gloss solid colours | Industrial housings, machine frames, general fabrication | Only an approximate match – anodising shifts the tone | Closest match inside the RAL range | Official RAL CLASSIC fan deck or authorised colour distributor | Screen and PDF values differ from the physical swatch |
| RAL 2000 – 2999 | Matt, satin and gloss solid colours | Machine tools, safety equipment, enclosures | Only an approximate match | Closest match inside the RAL range | Official RAL CLASSIC fan deck or authorised colour distributor | Screen and PDF values differ from the physical swatch |
| RAL 3000 – 3999 | Traffic and pastel shades | Signage, safety marking, decorative parts | Not recommended for clear-coated anodising | Good match with textured powder coat | Official RAL CLASSIC fan deck or authorised colour distributor | Confirm against the physical swatch before approving |
| RAL 4000 – 4999 | Purple and magenta shades | Design and decorative assemblies | Poor match – strongly affected by the base metal | Good match with textured powder coat | Official RAL CLASSIC fan deck or authorised colour distributor | Approve a production sample |
| RAL 5000 – 5999 | Blue shades | Machine housings, blue-passivated parts, branding | Reasonable match for light satin blue | Good match inside the RAL range | Official RAL CLASSIC fan deck or authorised colour distributor | Reflectivity changes the perceived tone |
| RAL 6000 – 6999 | Green shades | Enclosures, safety equipment, OEM branding | Reasonable match for dark green | Good match inside the RAL range | Official RAL CLASSIC fan deck or authorised colour distributor | Metallic effect shades vary strongly |
| RAL 7000 – 7999 | Grey shades | Machine frames, cabinets, structural parts | Good match for natural anodising grey | Excellent match inside the RAL range | Official RAL CLASSIC fan deck or authorised colour distributor | Most reliable RAL family for CNC aluminium parts |
| RAL 8000 – 7999 | Brown shades | Enclosures, trim and hardware | Poor match | Good match inside the RAL range | Official RAL CLASSIC fan deck or authorised colour distributor | Specify the finish code when ordering |
| RAL 9000 – 9999 | White, light grey and free whites | Clean-room and medical looking parts, panels | Good match for clear anodising | Excellent match inside the RAL range | Official RAL CLASSIC fan deck or authorised colour distributor | Free whites are not tied to a single colour sample |
The RAL colour values and the RAL logo are licensed, so this page does not publish digital colour values or swatches. It explains the nine colour families, how they behave on anodised aluminium and on powder coating, and where the official swatch has to come from. Always approve a physical production sample against the official fan deck.

Anodising shifts the tone of the base metal, so an exact match is only realistic in the grey, white and natural families. The RAL 7000 to 7999 grey range and the 9000 white range reproduce most reliably. Saturated blue, yellow and red shades should be agreed against a physical anodised sample.
No. A RAL number identifies a colour in the official system, but the appearance also depends on the material, the surface preparation, the film thickness, the alloy and the light source. A purchase order should reference the RAL number and also state the finish and the maximum gloss value.
Screens cannot show a calibrated colour, and every display has its own gamma setting. A digital value from a PDF or a website is a guide only, never a reference. The only reliable reference is the official physical swatch, ideally a fan deck from an authorised RAL distributor.
Send the RAL number together with the material, the surface finish and the coating type, for example powder coat to RAL 7016 matt. Ask for a production sample and approve it against the physical swatch before the batch is released. Any supplier that claims to match a RAL colour from a screenshot alone is guessing.
The grey families 7000 to 7999 and the whites of 9000 to 9999 are the most robust, especially on clear anodising. Metallic effect shades in 8000 and 9000 series are the least predictable because the effect depends on the viewing angle and the grain of the part.
The RAL colour system and the RAL logo are protected. Using the numbers to describe a finish in a purchase order is normal commercial practice, but reproducing the official colour values, swatches or digital files in a catalogue or a colour picker needs a licence from RAL.
