CMYK ↔ RGB Converter
Convert a color between CMYK print percentages and RGB or hex.
Bridge print and screen color
Design work constantly crosses between screen and print, but the two use different color models: RGB light for screens and CMYK ink for print. This converter moves a color between them so your print and web assets line up.
Pick a color or type CMYK percentages, and it shows the matching RGB and hex, using the standard subtractive formula. Because the two gamuts differ, treat the result as a close guide rather than an exact match.
Practical and private
It converts in both directions in your browser, so nothing you pick is uploaded. For critical print work, confirm against your press profile.
Frequently Asked Questions
Why do CMYK and RGB differ?
RGB is additive light for screens; CMYK is subtractive ink for print. They cover different gamuts, so a conversion is an approximation, not an exact match.
How is CMYK calculated?
K is one minus the largest RGB channel; the C, M, and Y values are then derived from the remaining channels relative to K.
Is this print-accurate?
It uses the standard formula, which is close, but true print color depends on paper, ink, and profile. Use it as a guide, not a proof.
