All tools
Deuteranopia Simulator
Paste hex codes and see how each looks with deuteranopia, using the Machado 2009 matrix in linear RGB. Pairs that merge into one tone are flagged.
Color Blender
Blend two hex colors at any ratio and get the mixed hex, RGB and HSL values, plus up to 20 evenly spaced in-between shades for a palette.
Color Converter
Convert a colour between HEX, RGB, HSL, HSV and CMYK from one entry, with relative luminance. Accepts #ff7f50, rgb(), hsl() or names like coral.
Compound Colors
Enter a hex colour and get a five-colour compound scheme: the complement, two split hues beside it and an analogous accent, each with hex and RGB.
