I would like to change the text color to bright green (#66FF00) but keep the default background color ( which is : "use system theme color ") of gnome-terminal. I can customize the text color, but in this case, I still need to specify the background myself. So I would like to know what's the RGB color of the default background color of gnome-terminal (in Ubuntu 10.04), and where I can find this value. Thanks.
Since at least 12.10, probably much earlier (source goes back to 2010-08), in Ambiance and Radiance themes, it's #300A24
.
Defined in: /usr/share/themes/*/gtk-*/apps/gnome-terminal*
.
Note that it's also slightly transparent (if compositing is enabled) - 5% if I'm reading the config right.
I was somewhat surprised that it's not one of the standard colors from Canonical's aubergine/orange palette.
