[CREATE] next... Tints, Tones and Shades... Linked colors

[Jon A. Cruz]

Time for the next question.

Do we need to handle tints, tones and shades? If so, in what way?


One simple way is to have % mix of white or black for tins and  
shades, and two %'s for tones (one for which gray, and one for how  
much).

A few apps support that in general, and I have code for Inkscape to  
support it too; I just need to expose it in a good manner.
