I just came across this table today and noticed a nit.

CMY colorspace and RGB color space have a very simple translation 
	[C,M,Y] = [1-R, 1-G, 1-B] (0..1 color values) 
between them.  The 16 widely know colors rename two of these colors.
	Fuchsia == Magenta
	Aqua    == Cyan
This makes very little sense to me.
