Color Area

Forms

About

A draggable 2D color plane for picking two channels at once (like saturation and brightness), with keyboard, RTL and form support.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Color Area to your project and fits it to your theme.

Code

How Color Area is used: the demo's code. The component's own source comes with a free account.
