[AUCTeX] setting same color for math scripts as other math

[Tamas Papp]

Hi,

I can't see the DarkRed very well and would like math scripts to have
the same color as other math in AUCTeX (burlywood in dark themes). How
can I achieve this in Emacs Lisp (I could customize, but prefer not to,
so that when I switch color themes it adjusts accordingly).

Is there some Emacs Lisp magic that would copy colors from one face to
another?

Best,

Tamas
