Customize the shared colors for the hub and all tools. Changes are saved in your browser and applied everywhere that uses global.css.

Surprise me picks a random coherent palette (e.g. forest, ocean, parchment) and applies it here—save to keep it. Save theme updates your local overrides and applies them immediately.
Reset to defaults restores the original palette values shown below but keeps the override system.
Clear custom theme removes all overrides so pages fall back to the values in global.css.
