Color Palette Generator API

br0ski777/color-palette-x402

Generates color palettes using classic color theory relationships: complementary, analogous, and triadic schemes. This is a remote server hosted at color-palette.api.klymax402.com that uses the x402 micropayment system, so you'll need compatible billing setup. The source repo doesn't expose much implementation detail, but the use case is straightforward: you need programmatic access to harmonious color combinations without rolling your own color wheel math. Useful when you're building design tools, theming systems, or anything that needs to suggest colors that actually work together. The SSE transport means it maintains a connection for streaming responses.
