About RGB and RAL
RAL Classic is a European standard of 213 numbered colors for paints, powder coatings and plastics, such as RAL 3020 Traffic red or RAL 7016 Anthracite grey. The first digit marks the group: 1 for yellows and beiges, 3 for reds, 5 for blues, 7 for greys and so on. RGB, by contrast, describes light on a screen, so there is no exact formula between the two — only a nearest match.
The tool converts your RGB color to the CIELAB space and compares it with every RAL Classic color using CIEDE2000, a formula that models how different two colors look to the human eye. The six closest colors are listed with their ΔE: below 1 is practically invisible, above 5 is clearly a different color. Click a match to compare it side by side and copy its code, or browse the whole chart sorted by number or hue. RAL screen values are approximations, so check your final choice against a physical RAL fan deck.
