Customize layout

Using ColorPickerProvider to wrap your custom layout and ready to use components:

import {
  ChannelInputs,
  ColorBox,
  ColorPickerProvider,
  EyeDropper,
  HueSlider,
  OpacitySlider,
  Presets,
} from '@chaos-synthesis/react-color-picker'
import { useState } from 'react'

const presets = [
  'rgba(255,0,0,1)', // Red
  'rgba(0,255,0,1)', // Green
  'rgba(0,0,255,1)', // Blue
]
const WIDTH = 300

function CustomColorPicker() {
  const [color, setColor] = useState('#CC00CC9F')

  return (
    <ColorPickerProvider color={color} onChange={setColor}>
      <div style={{ width: WIDTH, margin: '0 auto' }}>
        <ColorBox width={WIDTH} height={WIDTH} />

        <div style={{ display: 'flex' }}>
          <EyeDropper size={24} />

          <div style={{ margin: '14px 0', flexGrow: 1 }}>
            <HueSlider style={{ marginBottom: 12 }} />
            <OpacitySlider />
          </div>
        </div>

        <ChannelInputs inputType="rgb" />

        <Presets items={presets} />
      </div>
    </ColorPickerProvider>
  )
}

Check storybook for more component examples.

Customize components

Create your own components by using hooks:

import { useAlphaChannel, useHexStringColor } from '@chaos-synthesis/react-color-picker'

function CustomOpacitySlider() {
  const [value, setValue] = useAlphaChannel()
  const [background] = useHexStringColor()

  return (
    <input
      type="range"
      min="0"
      max="100"
      step="1"
      value={value}
      onChange={(e) => setValue(+e.target.value)}
      style={{ backgroundColor: background }}
    />
  )
}

Note: You should wrap your custom components with ColorPickerProvider to make them work. See Customize layout for example.
