The reason is that color blending in POV is based on linear interpolation
between the different color values in RGB space.  Although HSL color space
is somewhat different i don't think it would solve the problem.  

I think it would be an interesting feature to add an optional different
(and more realistic) color interpolation method to POV-Ray, not only for
antialiasing but also for color maps for example.
