How to add color themes to Gnome-Terminal's GUI preferences? I use Gnome-Terminal for a lot of my work, and like separating my windows by color based on the task that I'm doing, so I've set up several profiles using the Preferences GUI. I found some color themes online that I like and would like to use as a base for some of my profiles, including any that I create in the future. However, the Preferences GUI only has a few color theme options, and I would need to change all of the colors manually any time I want to use one of these custom themes. Is there a way I can add custom themes to my Preferences GUI? If that's not possible, is there another way I can easily set a custom color theme for a profile? I know I can manually change the colors in other places, like gconf-editor, but I'd prefer an easy way to just tell it the color theme by name and have it handle the rest (like what you can do with the GUI).

The color palettes are all hard-coded so adding custom themes to gnome-terminal built-in Prefs Menu is not possible unless you are willing to patch the source code and recompile the application.

One way of setting a custom color themes for your profile is via scripts. Have a look at how solarize does it:

Note, though, that gconf is EOL and future releases of gnome-terminal will use _gsettings_ backend.
