CMYK to RGB/Hex Converter

CMYK is the subtractive color model used in commercial printing. Cyan, Magenta, Yellow, and Key (black) inks absorb light rather than emit it — the opposite of RGB screens that add light. A business card, brochure, or magazine specifies colors as CMYK percentages: C=100 M=0 Y=0 K=0 produces a deep cyan. Web and mobile displays only understand RGB and Hex, so every print-to-digital workflow requires conversion.

Enter your four CMYK values as percentages from 0 to 100. The converter applies the standard transformation formula: each ink subtracts from white light, with black (K) reducing overall brightness independently. The result is three RGB channels (0–255) and the corresponding Hex code. Because CMYK gamut differs from RGB gamut, some vivid print colors cannot be reproduced exactly on screen — the preview shows the closest RGB approximation.

Designers receive CMYK specs from print vendors and need Hex equivalents for matching website headers to physical materials. Marketing teams maintain brand guidelines in CMYK for print collateral but need RGB/Hex for digital ads and social graphics. Understanding the conversion prevents surprises when a logo color looks different on paper versus on a monitor.

CMYK 0/0/0/100 is rich black for print, but on screen it converts to rgb(0, 0, 0) — the same as #000000. Light pastel CMYK values often produce very similar RGB results because low ink coverage maps to high RGB values across all channels.

Whether you are preparing a brand style guide that spans print and web, verifying a Pantone-to-CMYK-to-RGB chain, or learning why colors shift between media, CMYK conversion bridges subtractive printing and additive display.
