Hi Serg,

Thanks for the patch and sorry for taking so long in getting to it.

Like I said in the previous email this part doesn't really belong in the 
commit message. In fact, while this entire text is a good description of 
the patch and your efforts, it is not a good commit message.

Wouldn't having the contents of colored.tcl in themed.tcl be a good 
idea? The way I see it, colors are part of the theming of the 
application.

This is quite an improvement :-)

You can set that in the function `rmsel_tag` in git-gui.sh on the line

  $text tag conf in_sel -background lightgray

Do you mean to put the `-foreground` and `-background` options in the 
function ttext in themed.tcl? If so how can a widget specify if it wants 
a dark text or light for example?

FWIW I don't mind if you just put all this in the global namespace, but 
I'll leave it up to you.

Why have `textOnLight`, `textOnDark` and `textColor` separately? My 
guess is that it is for when you want to force light colors regardless 
of the theme? Am I right?

Nitpick: please use snake_case for variable names like the rest of the 
code does. Same for the function name below and the namespace name 
above.

Most of the patch looks good to me apart from my small suggestions. 
Thanks for working on this.
