# Conversion functions between RGB and other color systems.
#
# Define two functions for each color system XYZ:
# rgb_to_xyz(r, g, b) --> x, y, z
# xyz_to_rgb(x, y, z) --> r, g, b
# All inputs and outputs are triples of floats in the range [0.0...1.0].
# Inputs outside this range may cause exceptions or invalid outputs.
#
# Supported color systems:
# RGB: Red, Green, Blue components
# YIQ: used by composite video signals
# HLS: Hue, Luminance, S???
# HSV: Hue, Saturation, Value(?)

"""Conversion functions between RGB and other color systems.
This modules provides two functions for each color system ABC:

abc_to_rgb(x, y, z) --> r, g, b
All inputs and outputs are triples of floats in the range [0.0...1.0].
Inputs outside this range may cause exceptions or invalid outputs.
