Score: 6.0/10 (Innovation: 7, Technical: 7, Documentation: 5, Utility: 4)

Ray-color generates coherent color palettes by raytracing a sphere in a five-sided room with colored lights, sampling colors from the rendered surface. It offers a deterministic, dependency-free ~6 kB library with a WebGL2 preview and CPU fallback, enabling direct manipulation of lights and sample shapes.

Target audience: frontend developers, designers, generative artists
