Built-in themes

A theme sets the colours of Seshboard: the app, the code blocks and diffs, and the terminal, for light and dark mode. Seshboard comes with thirteen themes, and you can import your own.

Open it

• Press Command, Comma⌘,Control, CommaCtrl, (or click the gear at the bottom of the sidebar) and choose Theme.
• In the command palette (Command, K or Command, Shift, P⌘Kor⌘⇧PControl, K or Control, Shift, PCtrlKorCtrlShiftP), run Theme: <name> to switch to a theme, or Appearance: Match System, Appearance: Light or Appearance: Dark to change the mode. The palette only lists the choices you aren’t using now.

Choose light or dark

Appearance at the top of Settings → Theme has three choices:

• Match System (the default): follows macOSWindows, so Seshboard turns dark when your system does.
• Light
• Dark

The terminal panel is always dark, in light mode too.

Pick a theme

Click a theme card to use it. It applies at once, and a message in the corner says “Switched to <name>” with Undo, which takes you back to the theme you had.

Each card shows the theme in light and dark mode, its name, and who made it, with built in or imported. The theme in use has a ring in its own accent colour and a check mark.

Theme	Light mode	Dark mode
Demo Time (the default)	Demo Time Light	Demo Time Dark
Catppuccin	Latte	Mocha
Nord	uses Demo Time	Nord
Solarized	Solarized Light	Solarized Dark

Dark only

Nord has only a dark version, as the original does. Its card says Dark only. In light mode it shows Demo Time, and Settings says so under the cards: with Match System, light mode uses Demo Time.

Themes that match the app icons

Nine themes match the colourways of the app icon, each in light and dark: Graphite, Midnight, Paper, Signal, Forest, Plum, Aluminium, Ocean and Neon. Pick the icon and its theme together, or mix them as you like.

If you used the Claude or The unnamed theme, which are no longer built in, Seshboard switches to Demo Time.

More for a theme

Each card has a ⋯ button (or right-click the card, or press Shift, F10⇧F10Shift, F10ShiftF10):

• Export… saves the theme as a .json file. Exporting Demo Time gives you every colour, a good start for a theme of your own.
• Duplicate adds an editable copy to your themes.
• Show file and Remove are only there for themes you imported. Built-in themes can’t be removed.

See Custom themes for importing, exporting and editing theme files.

Settings

Everything on this page is in Settings → Theme. Your theme and appearance are part of the preferences you can back up.

A phone paired with Remote uses your theme too.
