Map colors across HEX, RGB, HSL, and CMYK for UI tokens and print-oriented workflows.
RGB is additive light for screens; CMYK is subtractive ink on paper with a smaller gamut. Some bright screen colors cannot be reproduced exactly in print.
HEX is simply a compact base-16 encoding of RGB channel values. #FF0000 and rgb(255, 0, 0) describe the same red on standard sRGB displays.
It converts color coordinates; it does not grade contrast ratios. Pair foreground and background colors in an accessibility checker when building UI.
