Product description area background in BO

[Jimbola]

Hi all

I have designed a site with a very dark brown coloured background.
The problem is when i go to the back office, add a new product, in the short/long product description areas the background comes up as dark brown and the text the same colour, making it impossible to see what i am typing, even if I change the font colour to black its difficult to see.

Is there a way to change the bgackground colour in those two areas so they are white? without affecting the front end?

All help is appreciated.
