Add White and Black as colors or make colors adjustable

[doublecookie]

I really like the look and ease of this programm, but it is nearly useless for me without white and black as colors
Would be super nice if one could change these or black and white are options by default
Thank you very much!

I will add a color palette when I get time. But, don't expect it soon.
