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.

Example sRGB codes (HEX · RGB · HSL)

HEXRGBHSL (rounded)
#3498DBrgb(52, 152, 219)hsl(204, 70%, 53%)
#E74C3Crgb(231, 76, 60)hsl(6, 78%, 57%)
#2ECC71rgb(46, 204, 113)hsl(145, 63%, 49%)
#FFFFFFrgb(255, 255, 255)hsl(0, 0%, 100%)

Illustrative sRGB examples; HSL matches integer rounding in the Color Picker UI.
