ColorBox is a free tool built for creating structured, flexible color palettes. It lets you generate custom color scales by adjusting hue, saturation, brightness, and step control. Colors can be fine-tuned across light and dark modes, with smart options for setting the number of steps or manually tweaking values until everything feels right.
The interface focuses on control without overcomplication. You can easily experiment with different color progressions, preview accessibility contrast levels, and generate matching dark mode palettes automatically or by hand. The tool provides real-time contrast checks so it is easy to spot potential issues before moving into design or development.
Finished palettes can be exported for Figma, downloaded in JSON, or copied straight into a codebase. It is fast, flexible, and built to help create color systems that feel intentional and consistent across a product. ColorBox is the kind of tool that solves a specific problem well, making color palettes that are easy to manage, accessible, and ready to use in any design system.
