I guess you're making a good point there, for why the way I'm aiming for 
is the right way to go: Making linear color space the default and fixing 
the places where it leads to noticeably unpleasant results. Because 
after all, I'm convinced that those places have always been problematic, 
but haven't been recognized as such because it wasn't that obvious as 
with a linear color space.

So yes, you've convinced me that we need to leave RGB space there. Maybe 
color map interpolation is a good place to start introducing color space 
handling into the POV-Ray code.
