Open Color is an open-source color scheme optimized specifically for use in UI elements, offering 13 colors each available in 10 carefully balanced shades. The palette is widely adopted as a design system foundation, particularly in developer-facing tools and open-source projects where a consistent, well-considered color base is needed. It is available in CSS, SCSS, and a range of design tool formats.
