CORE Theme Builder

About this plugin

The CORE Theme Builder is a fast, simple way to create structured color systems for your product. Set your base colors and the plugin generates a consistent set of shade primitives per group — ready to use across Light and Dark modes.Designed to work seamlessly with the CORE UI Kit, it lets you apply full themes instantly across components. You can also use it as a standalone tool to generate reusable primitives for any design system.FeaturesSurprise Me: one-click harmonized palettes using classical color-theory schemes (analogous, split-complementary, triadic, complementary), with saturation and lightness preserved so nothing gets brighter or darker — only the hue changes.Lock: pin a brand color and let Surprise Me harmonize the rest around it.Per-color control: create, update, or reset any color individually.Multi-step Undo: walk back through recent changes one step at a time.Token rebind: paste components from another CORE file and relink their remote tokens to your local theme in one click.Built for clarity, speed, and ease of use. Ideal for scaling design without slowing down.
