      "storybook-color-picker"
    ]
  };

Add palettes

Globally

This will add color picker and palettes everywhere in your storybook.

In your .storybook folder find preview.js file and add your color palette to parameters like below. Scroll down to find out how your color palette must look like.

import yourFirstColorPalette from './yourFirstColorPalette.json';
import yourSecondColorPalette from './yourSecondColorPalette.json';

export const parameters = {
  ...
  colorPicker: {
    primaryPalette: 'Your first palette name', // Name of primary palette for all components and its stories. Optional (fallback to first palette from the palettes array).
    palettes: [
      {
        name: 'Your first palette name', // string
        palette: yourFirstColorPalette, // Palette as an Object or an Array. See bellow.
      },
      {
        name: 'Your second palette name',
        palette: yourSecondColorPalette,
      },
    ]
  }
};

On component

This will add color picker and palettes to all component's stories.

In MyComponent.stories.js add:

export default {
  ...
  parameters: {
    ...
    colorPicker: {
      primaryPalette: 'Your first palette name',
      palettes: [
        {
          name: 'Your first palette name',
          palette: yourFirstColorPalette,
        },
        {
          name: 'Your second palette name',
          palette: yourSecondColorPalette,
        },
      ]
    }
  }
};

On story

This will add color picker and palettes to specific story.

In MyComponent.stories.js add:

export const Primary = Template.bind({});

Primary.parameters = {
  ...
    colorPicker: {
      palettes: [
        {
          name: 'Your first palette name',
          palette: yourFirstColorPalette,
        },
      ]
    }
}

Palette

as Object

type ColorPaletteAsObject = Record<string, Record<string, string> | string>;

Example:

  {
    "white": "#fff", // valid hex, rgb, rgba, hsl, hsla
    "black": "#000",
    "light": {
      " 500": "#aaa",
      " 100": "rgba(238, 238, 238, .8)",
      " 200": "rgb(238, 238, 238)",
      " 300": "hsla(0, 0%, 73%, .8)",
      " 400": "hsl(0, 0%, 73%)"
    },
    "dark": {
      "0100": "#888",
      "0500": "#000",
      "0400": "#222",
      "0200": "#666",
      "0300": "#444"
    }
  }

Useful tip: add white spaces or zeros before numerical keys to prevent auto sorting

as Array

  type ColorPaletteAsArray = {
    label: string,
    values: [
      {
        label: string,
        value: string,
      }
    ],
  };

Example:

  [
    {
      "label": "light",
      "values": [
        {
          "label": "100",
          "value": "#fff"
        },
        {
          "label": "200",
          "value": "#aaa"
        }
      ]
    },
    {
      "label": "dark",
      "values": [
        {
          "label": "100",
          "value": "#222"
        },
        {
          "label": "200",
          "value": "#000000"
        }
      ]
    }
  ]

Set primary palette on component or its stories

On component

This will apply for all component's stories.

In MyComponent.stories.js add:

export default {
  ...
  parameters: {
    colorPicker: {
      primaryPalette: 'Your second palette name',
    }
  }
};

On story

This will apply for specific story.

In MyComponent.stories.js add:

export const Primary = Template.bind({});

Primary.parameters = {
  ...
  colorPicker: {
    primaryPalette: 'Your first palette name',
  }
}

primaryPalette specificity:

The following list increases by specificity.

1. primaryPalette set on parameters in preview.js
2. primaryPalette set on component parameters
3. primaryPalette set on story MyComponent.parameters

Apply selected color to component's control

All controls with type of "color" will be detected automatically. You can add extra controls to which color may be applied. Only controls of type "text" may be added as extra.

On component

Add list of extra controls to all component's stories.

In MyComponent.stories.js add:

export default {
  ...
  argTypes: {
    backgroundColor: { control: 'color' }, // Color controls will be detected automatically
    label: { control: 'text' }, // Text controls may be added as extra
    text: { control: 'text' }, // Text controls may be added as extra
  },
  parameters: {
    ...
    colorPicker: {
      applyColorTo: ['label'] // Must match argType key
    }
  }
};

On story

Add list of extra controls to selected story to overwrite list added to component globally as in example above.

In MyComponent.stories.js add:

export const Primary = Template.bind({});

Primary.parameters = {
  ...
  colorPicker: {
    applyColorTo: ['text'], // Pass empty array to clear extra controls
  }
};

Default palettes

Disable default palettes

To disable default palettes just add disableDefaultPalettes: true to global, component or story parameters.

Theme

Storybook-color-picker will adjust automatically to the theme set on storybook.

To override the storybook theme:

export const parameters = {
  ...
  colorPicker: {
    theme: 'light' | 'dark' | 'auto' // Default 'auto'
  }
};
