HSL to RGB color conversion

Question

Hi I am looking for a tool to convert between HSL color to RGB. HSL is not a very widely used so I am not having much luck googling for a converter.

If you know of one, or an easily implementable algorithm it would be much appreciated.

Answer 1

The article for HSL and HSV on the wikipedia contains some formulas. The calculation are a bit tricky, it might be useful to take a look at existing implementations.

Answer 2

You can take a look at the Wikipedia's entry on HSL. There is a section that describes how the conversion from and to RGB can occur.

Answer 3

Found the easiest way, python to the rescue :D

colorsys.hls_to_rgb(h, l, s)

Convert the color from HLS coordinates to RGB coordinates.

Answer 4

Just noticed that the less.js project has a number of colour manipulation functions, including hsl_to_rgb:
