I haven't seen such a thing, but since it's cqcam I can probably explain 
it...  The program notices that the picture is red/brown and assumes that 
this is a problem with the lighting.  So it normalizes the colors when it 
shouldn't.

In most cases, this is a nice feature, since the color difference between 
incandescent light and sunlight is pretty dramatic, more than our eyes 
notice.  But in your case it's probably annoying.  :)  Just comment out 
(or remove) lines 58-63 in imager.C and recompile.  That's the 
do-RGB-adjust function.
