Dawn,
I completely understand what you are saying - my betta fish can look orange in one light and purple or green in another.
But the thing with the angelfish or crayfish is the actual color of their bodies changes over the course of months or if they were in certain lights since hatching.
Here's the link (but she talks about it in some of the other pages too): http://theangelfishsociety.org/articles/norton/dr_norton(10).htm
