Example:

{

  "plugin": [
    [
      "oc-plugin-rainbow",
      {
        "enabled": true,
        "fg": true,
        "bg": true,
        "speed": 0.008,
        "turns": 3,
        "glow": 0.05
      }

Open Rainbow settings from the command palette or run /rainbow-settings to tune the effect live. Those changes are stored locally per user.

Local use

Point a TUI config at the package directory:

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [["../../oc-plugin-rainbow", { "enabled": true }]]
}

The package exports its TUI entry at ./tui and provides default config via package.json.
