My pied girl is very high white, she turns a crazy shade of pink like yours when she goes into shed. She pretty much turns 'salmon' instead of 'blue'. I'm hoping that's all this is
That said.... burn is still possible so do make sure she's hydrated to help with the shed and the temps are correct. Nikkubus is correct about burns being hard to judge at first. The real damage isn't apparent until after they shed. When they burn they go into a shed cycle almost immediately and the tissue can take that bit of time to die off and slough with the shed skin.
After the shed is going to be when you get the answer, but do try to keep an eye for the next 2 weeks at least just in case.
