 ## Theme Files
 
 Theme files are stored as `<name>.json` in the `themes/` subdirectory of your config directory (`~/.config/ttt/themes/`). The filename (without `.json`) is the theme name used in `settings.json` and the theme picker.
+
+## Full Theme Reference
+
+Below is a complete theme file showing every configurable section. All color values are hex strings (`"#rrggbb"`). Optional `"bold"` and `"italic"` flags are supported where noted. Any field left empty (`{}`) inherits from the `default` colors.
