Colorzero is a library for working with colors in Python. It is not intended to be as comprehensive as colormath, but is intended to be a little easier to use, particularly for beginners. The major difference with colorzero is that colors are tuples and thus immutable. Standard mathematical operators (addition, subtraction, multiplication, etc.) are used to generate new colors. Conversions are provided for a wide variety of systems including YUV, RGB565, CMYK, CIE Lab, and so on.
