A designer sends a HEX code, your app needs RGB and a printer asks for CMYK. Converting by hand is slow and easy to get wrong.
How to convert
- Open Color Converter.
- Type a colour as HEX (#1E90FF), rgb(30, 144, 255) or hsl(210, 100%, 56%), or use the colour picker.
- Copy the format you need.
What each format is for
- HEX is the short code used in websites and CSS.
- RGB is how screens mix red, green and blue light.
- HSL describes hue, saturation and lightness, which is easy to adjust by hand.
- CMYK is for print. This tool gives a simple estimate, so always check proofs with your printer.
