How to change colors for ":sign" area in VIM?

Question

VIM supports :sign command that is widely used in debuggers to display graphical breakpoints to the left. How can i find correct names for background and foreground colors of this area in order to change them?

Answer 1

I believe you're looking for the SignColumn highlight group. For future reference, I found this by running :help highlight, then running the snippet found there that displays all active highlight groups (pasted here for convenience).

:so $VIMRUNTIME/syntax/hitest.vim
