CMYK to RGB Converter

Convert CMYK ink percentages to RGB screen colors instantly. Enter values like cmyk(60%, 40%, 0%, 20%) and get the RGB, hex, and HSL equivalents. All conversions happen in your browser.

CMYK to RGB Formula

CMYK values are converted to RGB by inverting the ink coverage. With C, M, Y, and K expressed as decimals from 0 to 1:

  1. Red: R = 255 × (1 − C) × (1 − K)
  2. Green: G = 255 × (1 − M) × (1 − K)
  3. Blue: B = 255 × (1 − Y) × (1 − K)
  4. Round each channel to the nearest whole number between 0 and 255.

Example: convert cmyk(60%, 40%, 0%, 20%) to RGB

C = 0.60, M = 0.40, Y = 0.00, K = 0.20

R = 255 × (1 − 0.60) × (1 − 0.20) = 255 × 0.40 × 0.80 = 82

G = 255 × (1 − 0.40) × (1 − 0.20) = 255 × 0.60 × 0.80 = 122

B = 255 × (1 − 0.00) × (1 − 0.20) = 255 × 1.00 × 0.80 = 204

Result: rgb(82, 122, 204)

How to Use the CMYK to RGB Converter

Enter your four ink percentages as cmyk(60%, 40%, 0%, 20%) or simply 60 40 0 20. The converter immediately shows the RGB equivalent along with hex, HSL, and CMYK round-trip values, each with a one-click copy button. The large preview swatch shows exactly how the color renders on screen.

From Ink Percentages to Screen Colors

CMYK is a subtractive model: inks absorb light, so higher percentages produce darker colors. RGB is additive: light is emitted, so higher values produce brighter colors. Converting between them inverts that relationship. Because the RGB gamut is wider than CMYK, every CMYK color has a faithful RGB representation - the reverse is not always true.

Common Use Cases

Designers digitizing legacy print assets, marketing teams turning brand books that only list CMYK values into web-ready hex codes, and developers reproducing packaging or editorial colors in apps and websites all rely on CMYK to RGB conversion.

Frequently Asked Questions about CMYK to RGB Converter

Each RGB channel is computed from its opposing inks: R = 255 × (1 − C) × (1 − K), G = 255 × (1 − M) × (1 − K), and B = 255 × (1 − Y) × (1 − K), where C, M, Y, and K are expressed as decimals from 0 to 1. Enter your percentages and the tool does this instantly.
