Possible to change colour color of foreground text "Total" column on Account Tree view?

[Graham Bygrave]

Hello,

I have a dark theme (helps with eyestrain) and can't see the positive figures 
in the Total column in the account tree view as the text is black as is the 
background.

Is there a way, either through configuration or through recompiling GnuCash 
that would enable me to change this colour to something lighter?

I'm using version 2.4.11.

Many thanks,
Graham.
