# 3rd selection argument is true to override default foreground # 4th selection argument is true to override default background selection=0x000000;0xc0c0c0;false;false
Edit 0xc0c0c0 to the colour you want and set the last false to true.
A weird thing with this is, at least when using the colour schemes support, when you have selected text and then open a modal dialog, the selection colours revert to some default grey colour which causes the OP's issues anyway. I haven't had time to pin down where the problem comes from, but I think it might be in Scintilla (and/or geany-themes).
Hi Matthew,
I don't think filetypes.common applies outside text in the Scintilla window, the normal dialogs and everything else is GTK theming using .gtkrc, see the manual for more info.
Cheers Lex
