Enhance Contrasts in Emacs GUI

[Wilmar Igl]

Dear Emacs developers,

I'd like to ask you to _enhance the contrasts_ in the Emacs GUI between 
Buffer Borders and text. The contrast between text and its borders or 
the scroll buttons and the background is rather low, which makes it 
sometimes difficult  to orient oneself especially if multiple buffers 
are displayed at the same time (and your monitor is not very good in 
contrasts). Maybe by adding some colored borders???
Thanks for your effort.

Yours,

Wilmar Igl
