-- This makes it easy to cycle through colors and compute color complements, triads, tetrads, etc.

|
|
-- Saturation is a number between 1 and 0 where lowering this number makes your color more grey. This can help you tone a color down.
|
|
--
|
|
-- Value is also a number between 1 and 0. Lowering this number makes your color more black.
