## What is it?

Color input plugin for [Sanity](https://sanity.io/) that stores selected colors in hex, hsl, hsv and rgb format.

![Color input in the Studio](https://github.com/user-attachments/assets/070a3718-33fc-47f7-94fb-93988902e81e)

## Installation

```
npm install --save @sanity/color-input
```

or

```
yarn add @sanity/color-input
```

## Usage

Add it as a plugin in sanity.config.ts (or .js):

```js
import {colorInput} from '@sanity/color-input'

export default defineConfig({
  // ...
  plugins: [colorInput()],
})
```

Now you can use the `color` type in your schema types:

```js
// [...]
{
  fields: [
    // [...]
    {
      name: 'favoriteColor',
      title: 'Favorite color',
      type: 'color',
    },
  ]
}
```

## Options

### Disable alpha

To disable the alpha option, set `disableAlpha` to `true`:

```js
// ...fields...
{
  name: 'favoriteColor',
  title: 'Color no-alpha',
  type: 'color',
  options: {
    disableAlpha: true
  }
}
```

Which will render accordingly:

### Color list

To add list of predefined selectable color swatches for the user to choose from use `colorList`.
The color picker is a small fork of [`react-color`](https://github.com/casesandberg/react-color), so `colorList` accepts any of its supported [color formats](https://casesandberg.github.io/react-color/#api-color).

```js
// ...fields...
{
  name: 'favoriteColor',
  title: 'Color with list',
  type: 'color',
  options: {
    colorList: [
      '#FF6900',
      { hex: '#FCB900' },
      { r: 123, g: 220, b: 181 },
      { r: 0, g: 208, b: 132, a: 0.5 },
      { h: 203, s: 95, l: 77, a: 1 },
      { h: 202, s: 95, l: 46, a: 0.5 },
      { h: 345, s: 43, v: 97 },
      { h: 344, s: 91, v: 92, a: 0.5 },
    ]
  }
}
```

Which will render accordingly:
