CMYK Converter

Convert RGB to CMYK and back, check total ink coverage, and find the nearest spot-colour approximation.

RGB 29, 78, 216 · CMYK 87 / 64 / 0 / 15 · Total ink coverage 166%

Inside the usual press limit (≤ 300%).

Type a hex code or drag the sliders; both directions update live.

Nearest spot approximation：Reflex blue (approx.)

Approximations only — official spot colour values are not published here.

Plain RGB↔CMYK conversion without ICC profiles — good for a first check, not a colour-managed proof.
