React-color is a powerful and flexible color picker library for React applications, offering developers a wide range of options to implement color selection functionality in their projects. With its diverse set of pre-built components and customization capabilities, react-color simplifies the process of adding intuitive color picking interfaces to your React applications.

Features

React-color comes packed with an impressive array of features that make it a go-to choice for developers:

  • Multiple Picker Types: The library offers 13 different color picker components, including popular styles like Sketch, Photoshop, and Chrome pickers.
  • Customization: Developers can use building block components to create custom color pickers tailored to their specific needs.
  • Flexible Color Formats: Support for various color formats including HEX, RGB, HSL, and more.
  • Responsive Design: All components are designed to work well on both desktop and mobile devices.
  • Accessibility: The pickers are built with accessibility in mind, ensuring a good user experience for all users.
  • Easy Integration: Seamless integration with React applications, with minimal setup required.

Installation

To get started with react-color, you need to install it in your React project. You can do this using npm or yarn:

Using npm:

npm install react-color --save

Using yarn:

yarn add react-color

Basic Usage

Once installed, you can start using react-color in your React components. Here’s a simple example using the SketchPicker component:

import React, { useState } from 'react';
import { SketchPicker } from 'react-color';

const ColorPickerComponent: React.FC = () => {
  const [color, setColor] = useState('#fff');

  const handleChangeComplete = (color: { hex: string }) => {
    setColor(color.hex);
  };

  return (
    <div>
      <h2>Choose a color:</h2>
      <SketchPicker
        color={color}
        onChangeComplete={handleChangeComplete}
      />
      <p>Selected color: {color}</p>
    </div>
  );
};

export default ColorPickerComponent;

In this example, we import the SketchPicker component from react-color. We use React’s useState hook to manage the selected color state. The SketchPicker component is rendered with two props: color (the current color value) and onChangeComplete (a callback function that updates the color state when a new color is selected).

Advanced Usage

React-color offers more advanced features and customization options for developers who need more control over their color pickers.

Custom Styling

You can customize the appearance of the color picker components using inline styles or CSS. Here’s an example of customizing the ChromePicker:

import React from 'react';
import { ChromePicker } from 'react-color';

const CustomStyledPicker: React.FC = () => {
  return (
    <ChromePicker
      styles={{
        default: {
          picker: {
            width: '300px',
            boxShadow: 'none',
            border: '1px solid #ccc',
          },
        },
      }}
    />
  );
};

export default CustomStyledPicker;

This example demonstrates how to modify the width, remove the box shadow, and add a border to the ChromePicker component.

Creating a Custom Picker

React-color allows you to create custom pickers using its building block components. Here’s an example of a simple custom picker:

import React, { useState } from 'react';
import { CustomPicker } from 'react-color';
import { Hue, Saturation } from 'react-color/lib/components/common';

const MyCustomPicker: React.FC = CustomPicker(({ hsl, hsv, onChange }) => {
  return (
    <div style={{ width: '300px', height: '200px', position: 'relative' }}>
      <Saturation
        hsl={hsl}
        hsv={hsv}
        onChange={onChange}
        style={{ width: '100%', height: '150px' }}
      />
      <Hue
        hsl={hsl}
        onChange={onChange}
        style={{ width: '100%', height: '20px', marginTop: '10px' }}
      />
    </div>
  );
});

const CustomPickerComponent: React.FC = () => {
  const [color, setColor] = useState({ h: 150, s: 0.5, l: 0.5 });

  return (
    <div>
      <MyCustomPicker color={color} onChange={setColor} />
      <p>Selected HSL: {`hsl(${Math.round(color.h)}, ${Math.round(color.s * 100)}%, ${Math.round(color.l * 100)}%)`}</p>
    </div>
  );
};

export default CustomPickerComponent;

This example creates a custom picker using the Saturation and Hue components from react-color. The CustomPicker higher-order component is used to wrap our custom picker, providing it with the necessary props and functionality.

Handling Alpha Values

If you need to work with colors that include alpha (transparency) values, you can use pickers that support alpha channels, such as the AlphaPicker or the RGBAPicker:

import React, { useState } from 'react';
import { AlphaPicker, RGBAPicker } from 'react-color';

const AlphaPickerComponent: React.FC = () => {
  const [color, setColor] = useState({ r: 200, g: 150, b: 35, a: 0.5 });

  return (
    <div>
      <h3>Alpha Picker:</h3>
      <AlphaPicker color={color} onChange={setColor} />
      <h3>RGBA Picker:</h3>
      <RGBAPicker color={color} onChange={setColor} />
      <p>Selected RGBA: rgba({color.r}, {color.g}, {color.b}, {color.a})</p>
    </div>
  );
};

export default AlphaPickerComponent;

This example demonstrates how to use both the AlphaPicker and RGBAPicker components to handle colors with alpha values.
