CMYK values (cyan, magenta, yellow, key/black, each 0-100%) are first converted to RGB with R = 255 × (1−C) × (1−K), G = 255 × (1−M) × (1−K), B = 255 × (1−Y) × (1−K), then each channel is written as a 2-digit HEX number. For example, cmyk(48%, 76%, 0%, 7%) = #7C3AED. This tool does the math automatically.
Enter your CMYK values in any common format: cmyk(48%, 76%, 0%, 7%), 48, 76, 0, 7, or 48 76 0 7. The tool is forgiving with spacing and punctuation. You can also use the color picker.

This converter uses the standard CMYK-to-RGB screen formula, which is a solid approximation for design and prototyping. For professional printing, check the result against your printer's ICC color profile - real ink and paper can shift the final color.
