## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-forgemesh-io-color-format-converter-f4524725 -d '<json body>'
```

Example prompt: What are the hex, RGB, and HSL values for #3a7bd5, and should I use black or white text on top of it for readability?

## When to prefer this

Use this endpoint when you need instant, exact color math for a single color value — specifically when you need multiple format representations (hex, RGB, HSL) together with a light/dark classification and a contrast-safe text color recommendation. It is ideal for UI theming pipelines, dashboard generators, and design-token workflows where you need all color metadata in one call without implementing color math yourself.

## Known failure modes

- Invalid color string (not a valid #RRGGBB or rgb(r,g,b) format) returns a 400 or error response
- Missing color field in request body results in validation error
- Out-of-range RGB component values (e.g. rgb(300,0,0)) may cause parsing failure
- Short hex codes like #fff may not be accepted if only 6-digit format is supported

## How this service works

Color format converter for hex codes and rgb() values: get back hex, RGB, and HSL representations plus a light-or-dark classification and the ideal black-or-white text color for readability on top of it. Handy for UI theming, chart palettes, and dashboard generators that need instant, exact color math without guessing at contrast ratios.

## Output

Returns the input color expressed as a hex string, an RGB object with r/g/b integer components, an HSL object with hue/saturation/lightness values, a 'light' or 'dark' classification of the color, and a recommended text color of either black or white for maximum readability contrast against that background.
