Very nice, reds are my favorite.

Zeke, they most often fire up at night when they are active. It usually has to be dark in order for this to happen (i.e., it could be night time, but if you have the lights on they probably won't come out and be active and get fired up). And if you don't have a red crested, you won't see that particular color when your gecko fires up. The intensity of the color varies as well--there are dull reds, intensely bright reds and everything in between.
