Calculator by Toolsloft ↗Enter a c, m, y, k value to convert
Convert a CMYK print color to RGB for use on screen, in CSS, or in code. Enter the cyan, magenta, yellow, and key (black) percentages and read the rgb() result. Useful when translating print-ready artwork into web colors.
How this is calculated
Each RGB channel is 255 times one minus its ink amount times one minus the black amount, using the standard CMYK to RGB formula. Note that screen RGB has a wider gamut than print, so this is an approximation of the printed color.
How to use
- Enter the cyan, magenta, yellow, and black values, for example 75, 50, 0, 20.
- The rgb() result appears below as you type.
- Copy the RGB values into your CSS or code.
Examples
- 75, 50, 0, 20:
rgb(51, 102, 204) - 0, 100, 100, 0:
rgb(255, 0, 0)
FAQ
- Will the RGB color match my print exactly?
- Not always. CMYK is a subtractive model for ink on paper and screens use additive RGB, so the conversion is a close approximation rather than a color-managed match.
- What does the K channel do?
- K is the black (key) ink. Raising K darkens every channel at once, which is why 0, 0, 0, 100 is pure black.
