Look and Feel

Themes

Customize the appearance of Sparky.

Sparky ships with built-in light and dark themes. You can switch between them from the settings page or ask the agent to do it for you.

Custom Themes

Create your own theme with a simple JSON file. Define a few base colors and Sparky derives the rest automatically. Drop the file into ~/.sparky/themes/ and it appears in the theme picker.

{
  "name": "GitHub Light",
  "bg": "#ffffff",
  "fg": "#1f2328",
  "accent": "#0969da",
  "mode": "light"
}

Only four colors and a mode are needed. Sparky derives all other shades (borders, surfaces, muted text) automatically from these base values.
