Match the plugin to your admin or your site. Light colours are darkened so text stays readable.
- Plugincy purple (default): the same look as other Plugincy plugins.
- Match my admin color: follows the color scheme you pick in Users → Profile.
- Match my site theme: uses your theme’s main color (block themes). Falls back to purple if your theme has none.
- Custom color: pick any color, or type a hex code.
Clicking a choice previews it at once. Click Save settings to keep it.
