Thighs and pads okay?

[dpcsquid]

I was hoping for everyone's opinions, please.

Does my frog's thighs look okay, color-wise? They just seem so much pinker than the rest of his underside, and I've heard concerns about red thighs.
In addition, hopefully you can see his front feet here--is it normal for him to have such WHITE pads in comparison to the rest of his foot? Or is this a sign of uncomfortable substrate?

Thanks so much for any help!
