Conversion functions between RGB and other color systems. This modules provides two functions for each color system ABC: rgb_to_abc(r, g, b) --> a, b, c abc_to_rgb(a, b, c) --> r, g, b All inputs and outputs are triples of floats in the range [0.0...1.0] (with the exception of I and Q, which covers a slightly larger range). Inputs outside the valid range may cause exceptions or invalid outputs. Supported color systems: RGB: Red, Green, Blue components YIQ: Luminance, Chrominance (used by composite video signals) HLS: Hue, Luminance, Saturation HSV: Hue, Saturation, Value
