Hue, from 0.0 to 360.0. Describes which color of the spectrum is
represented. A value of 0.0 represents red, as does 360.0. Values in
between go through all the hues representable in RGB. You can think of
this as selecting which color filter is placed over a light.
Saturation, from 0.0 to 100.0. This describes how colorful the color is.
0.0 implies a shade of grey (i.e. no pigment), and 100.0 implies a color as
vibrant as that hue gets. You can think of this as the purity of the
color filter over the light.
