Colors

This is a collection of functions for performing color operations, designed to work with the LÖVE game engine.

Documentation

Supports following color formats:

• rgb255: The standard computer representation, with each

channel (red, green, blue, alpha) in the [0-255] range. Alpha
channel (index 4), can either be explicit or implicit (and taken
to be 255.)

• rgb1: As above, except channels are in the [0-1] range.
• hsl: Hue-saturation-lightness representation (does not support alpha).

Hue channel is in the [0-1] range, instead of the standard [0-2*pi] range.
