powder paint colors after curing on two tone jigs

[ksgoosekillr]

i have been doing a lot of two tone painting lately. I'm starting to notice something and I'm hoping some other users here will have some good input on this. When doing two tone jigs ill use my last pour as an example, it was a a white undercoat, a chart yellow base with hot pink on the top and orange on the bottom. You can see the pics below... well this is before the curing. After i cured the jigs the hot pink on the top turned into orange. well more of a hot pink fade to orange. My question is what colors have you guys had change on you during curing? I just made a bunch of jigs the way i wanted them only to have them change on me.
