From HSL to RAL colors
HSL lets you describe a color the way you imagine it: a hue on the color wheel, how saturated it is and how light. That makes it a convenient starting point when you only have a rough idea — a muted blue-grey, a warm sand tone — and want to know which RAL Classic paint color comes closest.
Enter the three values, and the tool converts them to CIELAB and compares the result with all 213 RAL Classic colors using CIEDE2000, a formula designed to follow human perception. The six nearest colors appear with their code, name and ΔE; click one to compare it side by side. Tip: RAL Classic has many greys and muted shades but relatively few vivid ones, so a highly saturated HSL color often gets only a distant match — lower the saturation to see which RAL shades lie nearby.
All RAL screen values are approximate, so check a physical color card before ordering paint.
