Customization

Theme color

Section titled “Theme color”

The Liquid Glass theme color is set from Settings. Eight presets are available, and you can also pick a custom HEX value or use the color picker.

A special Ghostty preset reads background from ~/.config/ghostty/config. Text color (foreground) adapts automatically:

  • Ghostty preset: follows Ghostty’s foreground setting
  • Other presets: chooses white or black based on the theme color’s luminance

See the demo video.

Ghostty config compatibility

Section titled “Ghostty config compatibility”

Calyx reads the Ghostty config file at ~/.config/ghostty/config. Most keys hot-reload on save.

Some keys that conflict with the Liquid Glass UI are overridden by Calyx and won’t take effect.

Calyx-managed keys

Section titled “Calyx-managed keys”
  • background-opacity
  • background-blur
  • background-opacity-cells
  • font-codepoint-map
  • foreground

These are managed by Calyx to keep the Glass UI consistent. The full current list is shown in Settings under Ghostty Config Compatibility.

Clipboard paste confirmation

Section titled “Clipboard paste confirmation”

Calyx prompts before pasting potentially unsafe clipboard content. The behavior follows Ghostty’s clipboard-paste-protection setting. See Security & notifications for details.
