Theme

Ptah ships with a light and dark theme. The choice is stored globally in ~/.ptah/settings.json and applies to every workspace.

Changing the theme

• Settings → Appearance → Theme, or
• Edit ~/.ptah/settings.json:

{ "theme": "dark" }

Value	Behavior
light	Always use the light theme
dark	Always use the dark theme
system	Follow the OS appearance preference and update live when it changes

High-contrast mode

High-contrast variants of both themes are derived automatically when your OS reports a high-contrast preference. No additional setting is required.

Accent color

The brand accent is fixed in the current release. Custom accent colors are on the roadmap.
