Notification popup color customization
problem
The notification popups colors are currently hardcoded, and some people might not like the default color (and it might not integrate well with some themes).
analysis
This should go in the config, imo, with sane defaults (the current values).
enhancement recommendation
I have attached a patch that should do it (had to replace the "named" colors by their hex value, because the opt_color type doesn’t match the names).
