A CSS color system with better default colors for web development and prototyping.
Colors.css is a lightweight CSS color system that provides better default colors for web development. It offers a collection of utility classes for applying consistent, aesthetically pleasing colors to backgrounds, text, borders, and SVG elements.

Frontend developers and designers who need quick, consistent color application in web projects, particularly those using utility-first CSS approaches or rapid prototyping workflows.
Developers choose Colors.css for its minimal footprint, carefully curated color palette that works well together, and comprehensive utility classes that cover all common color use cases. It integrates easily with existing CSS workflows and build tools.

Full customization requires using tachyons-cli or similar tools, adding setup complexity for simple color changes.
