# Themes

Switch in **Settings → Appearance**. Four themes ship with Orbit:

- **Light** — the clean default.
- **Dark** — low-light palette.
- **yomIRC** — a faithful retro mIRC / Windows-95 skin: silver 3D-bevelled chrome, fixed-width log
  lines (`[HH:MM] <nick> text`), a flat nick list. For the nostalgic.
- **yomIRC dark** — the retro skin in a deep dark palette with a teal accent.

Deployers can set the **default theme** for new users in
[`config.json`](/docs/config/) → `defaults.theme` (`light` · `dark` · `yomirc` · `yomirc-dark`).

Other appearance options in Settings:

- **Compact mode** — denser message rows.
- **Time format** — 12h / 24h timestamps.
