To make it somewhat easier, look at the color in the HSB (Hue
Brightness) model, and then you just reduce the Brightness to create a
shadow color. The Shadow thickness could be a percentage between 0%
color has same brightness as original color, and hence, it is the same
color) and 100% (full black shadow).
