Convert any CMYK value to a HEX color code instantly — the bridge between print artwork and web design.
CMYK (cyan, magenta, yellow, key/black) is a subtractive color model used by physical printers; HEX (and RGB) is an additive model used by screens. The two gamuts overlap but are not identical, so there is no perfectly faithful conversion — only a best approximation.
ColorUI uses the standard formula: each channel converts to RGB by R = 255 × (1 − C) × (1 − K), and similarly for G and B, then RGB encodes to HEX.
Use this when you have brand colors specified in CMYK (from a print designer) and need to ship the closest web equivalent.

No — CMYK and sRGB have different gamuts and the result depends on paper, ink and lighting. The HEX value is the closest screen approximation.
R = 255 × (1 − C) × (1 − K), G = 255 × (1 − M) × (1 − K), B = 255 × (1 − Y) × (1 − K). Then encode each channel as two hex digits.
Yes. No sign-up, no usage limits.
HEX, RGB, HSL, HSV, LCH, OKLCH and LAB — all in one tool.
