Enhance Contrasts in Emacs GUI (with additional comments)

[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???

Another helpful, user-friendly feature could be to color new messages, 
or input requests in the minibuffer, to attract the attention of the 
user. This could also be applied to windows that pop up (cf. reminding 
of appointments).

Thanks for your effort.

Yours,

Wilmar Igl
