How to use the CMYK to RGB Converter
Choose a conversion direction to switch between editing CMYK percentages or RGB channel values
Drag each slider or type a number directly into the field next to it for precise control
Type or paste a hex code and click Apply Hex to load that color into the current mode
Click any preset swatch to instantly load a common print or screen color
The All Formats tab lists the hex, RGB, CMYK, HSL, and CSS device-cmyk representations of the current color
Use the Copy button next to any row to copy that exact value to your clipboard
The Contrast Check tab shows the WCAG contrast ratio of the current color against pure white and pure black
Click Save Color to add the current color to a temporary session history you can revisit later
Use the Saved Colors tab to restore any previously saved color back into the editor
Total Ink Coverage adds up all four CMYK channels, which is useful for checking against print shop ink limits
CMYK to RGB conversion follows the standard subtractive color formula used across design software
RGB to CMYK conversion derives the key channel from the darkest of the three color channels
Results are an approximation since real CMYK printing depends on the specific ink set and paper used
All math runs locally using plain JavaScript formulas. Nothing is ever sent to any server
