What is Palette Generator?

Color Palette Generator creates balanced, aesthetic 5-color palettes based on classical color theory principles. Explore complementary, triadic, analogous, monochromatic, pastel, and high-contrast dark-mode schemes with 1-click export to CSS variables or Tailwind configs.

Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.
