## About

## What it does
Color Converter takes a single color value and returns a structured JSON response for using that color across your product stack. Send a color in `#rrggbb`, `rgb()`, or `hsl()` format, and use the result to standardise design tokens, generate palette variants, or feed color data into UI tooling.

Use Color Converter when you need to normalise user-supplied colors or move between common CSS color models without writing your own parsing logic. It is useful in design systems, theme editors, brand asset pipelines, and front-end tools that need consistent color handling.

Because the endpoint accepts a single `color` value, it returns the color in multiple formats such as HEX, RGB, HSL, HSV, and CMYK, along with accessibility information and matching color palettes., it fits cleanly into validation steps, admin interfaces, and automation workflows where colors may arrive in mixed formats. The response includes color conversions, accessibility information, and generated color palettes that can be used directly in design and development workflows.

If your app stores colors, renders previews, or checks contrast for accessible UI choices, Color Converter gives you a predictable way to transform and reuse color values without handling format conversions yourself.
