Are you using "#version 3.7"? If yes, then you need to either:
1) define your colors using 'srgb' instead of 'rgb' (and use 'assumed_gamma'
with image maps),
2) use "assumed_gamma 2.2" in the global_settings block if you want to get
the same gamma behavior as with POV-Ray 3.6, or
3) remove the #version directive (or use "#version 3.6"), which achieves
the same as option 2 above.
It is generally recommended to use option 1, but when transferring a scene
from 3.6 to 3.7 it may be more convenient to use one of the other two options.
(Also things like color maps cannot yet be replicated in 3.7 using the
default assumed_gamma 1.0, so that might be another situation where you
may need to compromise and use assumed_gamma 2.2.)
