CMYK to HEX / RGB converter for print designers — how do I preview brochure ink colors on my monitor?
Use a simple CMYK→sRGB formula for on-screen preview: each channel uses 255×(1−ink)×(1−black). This site applies the same model as the Color Picker and picks RGB that round-trip when you copy CMYK from the picker (integer CMYK can match more than one RGB).
Detailed answer
Real print depends on paper, ink, and ICC profiles; browser tools show an approximation. Enter cmyk(c%, m%, y%, k%) on CMYK to HEX or CMYK to RGB, read the breakdown lines, then compare with the main Color Picker if you started from a screen color.
Relationship context
CMYK is subtractive (ink); RGB is additive (light). They meet through math models, not a single universal “exact” pair without a profile.
