Appearance and themes

Switch between light and dark, pick a theme, or build your own colors and fonts — applied across the whole app.


Kaizendex's colors and fonts are controlled by themes. You choose how the app looks — light or dark, which palette, which fonts — and it applies everywhere: sidebar, cards, buttons, charts.

You'll find it all in Settings → Appearance. On desktop, open Settings from the gear icon next to your name at the bottom of the sidebar; on phone, tap Settings in the bottom bar. Then pick Appearance.

Light, dark, or system

The mode toggle decides which theme is showing:

  • System — follows your device's light/dark setting and switches automatically.
  • Light — always your light theme.
  • Dark — always your dark theme.

You keep two themes active at once — one for light, one for dark. Mode just picks which slot is on screen. So you can set a warm light theme and a deep dark theme, leave mode on System, and Kaizendex flips between them with your OS.

Picking a theme

Each slot (light and dark) shows a library of themes to choose from:

  • Built-in themes ship with the app and are always available.
  • Your own themes appear alongside them once you create any.

Click a theme to make it the active light (or dark) one. The whole app re-colors instantly.

Making your own

To customize, duplicate a built-in theme — that gives you an editable copy you own. In the theme editor you can change:

  • Colors — each part of the interface (background, surfaces, text, the accent color, borders, and more) is a named slot you can recolor.
  • Fonts — pick from the bundled font set for the app's body, monospace, and display text.
  • Region tweaks — nudge just one area (say, a darker sidebar) without touching the rest.

There's also a raw JSON editor for power users and for pasting a theme the AI generated for you — it validates as you go and rejects anything malformed.
