Customizable colors!

[girins]

Hello everyone, i don't know if it's already a feature but i couldn't found it anywhere:
there is or there could be the possibility to customize font colors and background colors? 
or at least have a few oprtional themes to choose, i tend to use dark themes or high contrast ones.
Thankyou!

Radegast should be using Windows system theme, so if you chose high-contrast it should do it automatically.

Or are you on Linux?

thank you for the smart trick! it works perfectly, but maybe a little color customization in the preferences menu would be useful for fine tuning it!
apart that the viewer is great! (I am actually on win8 but i installed it also in an easypeasy distro of linux and it worked easily, even if i couldn't test if all the features were operative)
