gnumeric dark theme

[Fourhundred Thecat <400thecat gmx ch>]

Hello,

I am using dark desktop theme (light text on dark background).

But gnumeric is using black text on white background.

Is there some way to either:

 a) tell gnumeric to use my gtk theme, as all other applications

or

 b) configure myself color for background and text in gnumeric ?

I am using gnumeric 1.12.44-1 on Debian Buster.

thanks,
