Looking to plasma themes as an example, how do you deal with 'I need the 
dark shade of the neutral foreground color of the window set'? That's 
not that unusual a request, especially if you start talking about themed 
icons. Sure, you can create a LOT of named colors, but my suggestion is, 
I think, actually LESS complex, and a whole lot more powerful.

Or do you mean to somehow have in the .svg a color name that would be 
replaced instead of a replacement table? If so, how would you do that 
(besides hand-editing the .svg)?

The replacement table idea would work perfectly well with gradients (at 
least so far as you would replace the stop colors the same as anything 
else). I'm not sure how you could define to replace a solid color with a 
gradient, since you need directionality (and how do you specify the 
coordinates?).
