Hog Island Pink belly

I've noticed my hogs belly is always pink, is this just how it is, or is something wrong??

I keep her on aspen, 90warm/80cool, I don't think 90 is too high, is it????

That's how it is.

Ours has a pink/peach color to it. I don't believe 90 is too high as long as she has room to thermoregulate. Our girl is in a 4ft vision cage and is very good about moving from cool side to warm side.

Ok I'm just making sure. I've heard they are more dull at night, which I have witnessed in the past couple of days, and the pink seems a little more prominent when she's in her darker "phase".
