The galacts have a lot of different color forms and patterns varying from bright red (with is a distinct morph)through orange, yellow with different line patterns and shades. Mine were called "pumpkin orange splash-backs" by Patrick when I purchased the first ones 8 years ago or so. Your friend may just have a different color or pattern line. (I'm not sure these are all actually distinct morphs from different areas.)
Anyway, to babble off on a tangent: These ladies faded out a great deal with age, in spite of paprika on the flies. Last year, I bought three more juveniles of the same line to amuse them. The contrast was striking, as the juvies were so brilliantly orange. I then cheated and began adding Naturose powder to my vitamin dusting mix. Now, it's hard to tell the difference between the old girls and the young adults. So it's either the Naturose or the stimulation of the added frogs, or both, but it also seems to be coloring up my faded-out pumilio Bastimentos, which started out as a very red-orange.
Naturose is a fish product made from Haematococcus algae with a lot of carotenoids including astaxanthin, which enhances the reds in particular, when it's stored in the chromophores. I believe the Betta carotene in paprika is stored as a more yellow color than orange or red.
I don't think most dart colors fade in nature, so perhaps our food items simply don't contain the same kinds of carotenoids and such as their wild diets. At least, that's my excuse for "cheating," if one can actually call it that.
