Dionaea in dark containers

Have any of you found Dionaea to be sensetive to higher than "normal" soil temps?
I have a rather attractive black glazed ceramic pot into which I planted a VFT "Green Dragon" from PFT. I am worried about the soil getting a little warm when the sun hits the pot in the summer.
Thoughts?

I don't like dark containers. But white ones are a little hard to find, so I use 4" green ones. It gets really hot during the summer when exposed to direct heat, but the plants don't seem to mind.
