Introduction

react-color-tools provides a set of tools as React components for working with colors. These tools can be used to manipulate a color for example controlling the intensity or purity of color, extracting swatches from an image, creating a gradienty defining color stop positions, choosing from variety of shades and tints or choosing a color scheme.

Motivation

react-color-tools is inspired from react-color. I was using react-color for my projects and felt the need for more features like image color extraction, generating shades and tints, creating gradients, and advance color tools for controlling the intensity and value of the color. So I decided to build react-color-tools with these features while keeping the API surface minimal and easy to use.

Features

• Image color extraction

• Generate shades and tints

• Built-in color manipulation tools

• Create gradient by controlling the color stop positions

• API for color conversions

• Color scheme picker

Use cases

• Managing color schemes

• Design systems & creating design tools

Theory

A little bit about different color terms and color harmonies that you will be using while working with react-color-tools.

Color terms

• Hue - A hue is name of particular color, or it is also one of the 12 colors on the color wheel.

• Shade - A shade is a hue darkened with black.

• Tint - A tint is a hue lightened with gray.

• Saturation - Describes the intensity or purity of color.

• Desaturation - Desaturation makes a color look more muted (hue approaches closer to gray).

Color schemes

• Monochromatic - This color scheme contains tints, shades and tones of a color.

• Analogous - This color scheme contains the hues that are located side by side on the color wheel.

• Split Complementary - This scheme represent any color on the color wheel plus two colors that are it's complement.

• Triadic - This color scheme has three colors that are evenly spaced on the color wheel.

• Tetradic - Two pairs of colors which are opposite on the color wheel

Install

npm install react-color-tools

or if you use yarn,

yarn add react-color-tools

This package also depends on React so make sure you've it installed.

Usage

import React from 'react'
import { render } from 'react-dom'
import { BasicPicker } from 'react-color-tools'

class App extends React.Component {
  state = {
    color: 'hotpink'
  }

  render() {
    return (
      <div>
        <BasicPicker
          color={this.state.color}
          onChange={color => this.setState({ color })}
        />
        <h1 style={{ color: this.state.color }}>React Color Tools</h1>
      </div>
    )
  }
}

This will render -

TODO

• Use a monorepo format to store different pickers and color tools

• Tweak rollup config to reduce bundle size

• Remove tooltip styles and use react-emotion to create tooltip component

• Add bezier easing to gradient picker component
