Settings

Appearance

Light, dark or system; the five bezel base colours; font sizes.

Settings → Appearance controls how Sirio looks.

Mode

System, Light or Dark. The palette is bezel’s, the same UI library the app is built from, with Sirio’s own coral for the brand mark and body text pulled back a little from full contrast to reduce glare.

Base colour

The greys carry a chosen hue: Neutral, Stone, Zinc, Gray or Slate. Only the hue moves. Lightness stays fixed, so every family keeps the contrast Sirio verified in the shipped palette. Status colours, the brand coral, the terminal surface and the borders do not rotate.

Font sizes

You set the interface font size and the terminal font size separately. The interface uses Geist; the terminal uses Geist Mono, falling back to JetBrains Mono.
