Material takes cues from contemporary architecture, road signs, pavement marking tape, and athletic courts. Color should be unexpected and vibrant. (https://material.google.com/style/color.html)

Material color hashing

Hash a string to a Material Design color

A dead-simple library to hash a string to a {backgroundColor, textColor} tuple from the official Material Design palette.

Great for dynamically coloring your UI elements (badges, list icons, ..) with good-looking, vibrant colors and ensured text legibility.

Usage

$ npm install material-color-hash

var toMaterialStyle = require('material-color-hash');
// or, if you are on ES6:
// import toMaterialStyle from 'material-color-hash'

/* basic usage */
var fooStyle = toMaterialStyle('foo');
// fooStyle: {
//   backgroundColor: '#00BCD4',
//   color: 'rgba(0, 0, 0, 0.87)',
//   materialColorName: 'Cyan'
// }

/* select a different shade (default is 500) */
var fooStyle200 = toMaterialStyle('foo', '200');
// fooStyle200: {
//   backgroundColor: '#80DEEA',
//   color: 'rgba(0, 0, 0, 0.87)',
//   materialColorName: 'Cyan'
// }

var barStyle = toMaterialStyle('bar', 500);
// barStyle: {
//   backgroundColor: '#2196F3',
//   color: 'rgba(255, 255, 255, 1)',
//   materialColorName: 'Blue'
// }

/* also works with emoji! */
var emojiStyle = toMaterialStyle('😎');
// emojiStyle: {
//   backgroundColor: '#FFEB3B',
//   color: 'rgba(0, 0, 0, 0.87)',
//   materialColorName: 'Yellow'
// }

The returned object can be fed directly as a style prop to React components:

import toMaterialStyle from 'material-color-hash';

const MaterialBadge = (props) => {
	const style = toMaterialStyle(props.text);

	return (
		<div
			className="badge"
			style={style}
		>
			{props.text}
		</div>
	);
}
