Color Palette Generator – Build Accessible, Export‑Ready Color Systems from Images, Websites, or Seed Colors
Color Palette Generator is an advanced online tool to extract, generate, and refine harmonious color schemes for branding and UI design. Create palettes from a website URL, uploaded image, or base color; validate WCAG contrast; and export CSS variables and JSON for instant integration.
What is a Color Palette Generator?
A color palette generator helps designers and developers craft cohesive color systems by analyzing inputs and outputting scalable palettes with HEX, RGB, and HSL codes. It streamlines color discovery, accessibility checks, and code‑ready export for design systems, apps, and websites.
How it works
- Choose input: paste a website URL, upload an image, or start from a seed color to initialize the palette.
- Generate palettes with controls for palette size, hue bias, saturation/lightness balance, and randomization.
- Validate contrast against WCAG AA/AAA and preview text on backgrounds, buttons, badges, and UI elements.
- Export results as CSS variables, Tailwind‑style tokens, or JSON to plug directly into your codebase.
