-"""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
