 The picker works offline with 1,870 emoji from [gemoji v4.1.0](https://github.com/github/gemoji/tree/v4.1.0). Its [MIT license](Sources/ConjureKit/Resources/LICENSE-gemoji.txt) is included in the application.
 
+## Color scheme
+
+Create `$XDG_CONFIG_HOME/conjure/config.json`, or `~/.config/conjure/config.json` when `XDG_CONFIG_HOME` is unset, empty, or relative. No configuration is required: Conjure keeps its built-in sunset colors by default.
+
+```json
+{
+  "colors": {
+    "background": "#171b24",
+    "text": "#e0e6f0",
+    "secondaryText": "#a0adc0",
+    "accent": "#82aaff",
+    "glow": "#c792ea",
+    "keyBackground": "#303848",
+    "error": "#ff5370"
+  }
+}
+```
+
+Every color is optional and must be an opaque `#RRGGBB` value. `accent` colors selections, borders, carets, and the primary background glows; `glow` colors the secondary background glow. `keyBackground` colors application-number shortcut badges, and `error` colors errors and destructive actions. Overrides apply throughout the launcher, tools, popups, and Settings wherever those shared colors are used.
+
+Only colors change. Frosted glass, glow positions and sizes, opacity, selection treatment, typography, and layout stay fixed. Native controls, application/emoji icons, and Notes code-syntax highlighting retain their existing styling.
+
+### Follow tint
+
+The sibling [tint](../tint) tool generates `conjure/theme.json` in the same configuration directory when it applies a theme. Rebuild/install the updated tint tool with `make install` in its repository, then apply your chosen pair, for example `tint swamp`. Opt in from Conjure's `config.json`:
+
+```json
+{
+  "theme": "tint",
+  "colors": {
+    "accent": "#82aaff"
+  }
+}
+```
+
+Precedence is personal `colors` → tint-generated colors → built-in sunset colors. Omit `colors` to follow tint without overrides. Omit `theme`, or set it to `"sunset"`, to ignore the generated palette. tint never overwrites `config.json`; edit that file, not the generated `theme.json`. Both processes must use the same configuration directory.
+
+Conjure reads colors once at launch. Quit and reopen it after editing configuration or applying a tint theme, including automatic light/dark switches. Invalid JSON, unknown keys, unsupported themes, invalid colors, or a missing selected tint palette cause a full fallback to sunset and a file-specific error in Settings. Normal launches open Settings to show the error; login launches leave it available for the next time Settings opens.
+
 ## System theme
 
 Search for **Toggle System Theme**, identified by its centered 🌗 icon (try `theme` or `system`), and press Return to switch macOS from light to dark appearance or back. Selecting it in the launcher dismisses Conjure on success. Its global shortcut runs in the background without presenting a window or changing the current launcher view. You can favorite it or assign a shortcut in Settings; existing theme keybindings and favorites survive the rename.
 
-The first use may ask permission to control **System Events**. Allow it under **System Settings → Privacy & Security → Automation → Conjure**. If permission is denied or macOS reports an error, Conjure shows the failure in the visible launcher or a standalone alert when the launcher is hidden. Conjure's own launcher keeps its existing dark styling.
+The first use may ask permission to control **System Events**. Allow it under **System Settings → Privacy & Security → Automation → Conjure**. If permission is denied or macOS reports an error, Conjure shows the failure in the visible launcher or a standalone alert when the launcher is hidden. Conjure's own launcher keeps its configured colors and existing presentation; switching macOS appearance does not reload its palette.
 
 Commands explicitly declare `Application.Command.presentsView`. The shared dispatcher routes action-only commands before any launcher presentation; new commands must choose their behavior in the exhaustive metadata switch. Command IDs remain independent of display names so renaming does not reset saved shortcuts, favorites, or usage.

-- [ ] feature: configurable color scheme
+- [x] feature: configurable color scheme
     - general design should stay consistent
     - only colors should be configurable; not the way the colors are used/presented (e.g. frosted glass effect with color blobs behind shouldn't change)
     - this should play nicely together with the theme control tool in `/Users/valdemar/Developer/Personal/Tools/tint`.
