# Themes
This section explains how you can go about themeing the {{Terminal}} node.
## Default
If you add a {{Terminal}} node to your scene without any themes or theme overrides, then the default theme will apply.
This default theme is based on the default theme that Godot uses for the {{TextEdit}} and {{CodeEdit}} nodes.
### Font
[JetBrains Mono](https://www.jetbrains.com/lp/mono/) is the default font.
This is the same default font as the Godot code editor (since version 4).
It is not included with the default theme, so we bundle it separately.
:::{caution}
Only the regular version of the font is included. The **bold**, _italic_, and **_bold italic_** variants are not.
If you want these, you'll need to include them in a custom theme.
:::
:::{error}
This font has support for ligatures (see: [Ligatures for Code](https://github.com/JetBrains/JetBrainsMono?tab=readme-ov-file#ligatures-for-code)).
While the engine supports this feature, GodotXterm currently does not, and there are no immediate plans to support it.
:::
The default font size is 16.
### Colors
GodotXterm uses the same default font color and background color as Godot's {{TextEdit}} and {{CodeEdit}} nodes.
:::{note}
The default background color of Control nodes is intentionally traslucent.
See [the discussion](https://github.com/godotengine/godot/pull/51159#issuecomment-891126656) on the Godot GitHub repo about this.
:::
The default ANSI colors are the same as [the xterm defaults](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors).
