Custom colour schemes can be created here and then selected on the appearance tab of the connection profiles.

There are 16 colour codes which can be modified. The defaults conform to the ANSI standard. In most situations, the values 0 and 7 are used for background and foreground respectively. The "Background" and "Text" buttons on this page are a shortcut to the values 0 and 7.

Any changes you make here will be shown in the preview window so you can see how they look before saving. You can either change the default colour scheme which will then effect all profiles, or create your own custom scheme and assign it to specific profiles.

If you delete a colour scheme, any profiles using that scheme will fall back to the default scheme. You cannot delete or rename the default scheme.
