Color Converter – Convert Color Online (Free Tool)

Color Converter takes one colour and gives you HEX, RGB, HSL and CMYK simultaneously. The built-in manipulation panel also generates lighter, darker, more saturated and mixed variants in HSL space — useful for building a small palette around a brand colour without leaving the page.

CMYK percentages look slightly different from Photoshop.
