Generate color based on the given string (using HSL color space and SHA256).
npm install color-hashGenerate color based on the given string.

``typescript`
import ColorHash from "https://deno.land/x/color_hash@v2.0.0/mod.ts"
`bash`
npm install color-hash
`typescript`
import ColorHash from 'color-hash'
or
`javascript`
const ColorHash = require('color-hash').default;
`html`
#### Basic
`javascript
var colorHash = new ColorHash();
// in HSL, Hue ∈ [0, 360), Saturation ∈ [0, 1], Lightness ∈ [0, 1]
colorHash.hsl('Hello World'); // [ 225, 0.65, 0.35 ]
// in RGB, R, G, B ∈ [0, 255]
colorHash.rgb('Hello World'); // [ 135, 150, 197 ]
// in HEX
colorHash.hex('Hello World'); // '#8796c5'
`
#### Custom Hash Function
`javascript`
var customHash = function(str) {
var hash = 0;
for(var i = 0; i < str.length; i++) {
hash += str.charCodeAt(i);
}
return hash;
};
var colorHash = new ColorHash({hash: customHash});
colorHash.hsl('Hello World!');
colorHash.rgb('Hello World!');
colorHash.hex('Hello World!');
#### Custom Hue
`javascript`
var colorHash = new ColorHash({hue: 90});
`javascript`
var colorHash = new ColorHash({hue: {min: 90, max: 270}});
`javascript`
var colorHash = new ColorHash({hue: [ {min: 30, max: 90}, {min: 180, max: 210}, {min: 270, max: 285} ]});
#### Custom Lightness
`javascript`
var colorHash = new ColorHash({lightness: 0.5});
`javascript`
var colorHash = new ColorHash({lightness: [0.35, 0.5, 0.65]});
#### Custom Saturation
`javascript`
var colorHash = new ColorHash({saturation: 0.5});
`javascript`
var colorHash = new ColorHash({saturation: [0.35, 0.5, 0.65]});
MIT.
It uses the hash function (default is BKDRHash) to calculate the hash of the given string.
`
Hue = hash % 359. (Note that 359 is a prime)
Saturation = SaturationArray[hash / 360 % SaturationArray.length]
Lightness = LightnessArray[hash / 360 / SaturationArray.length % LightnessArray.length]
By default,
SaturationArray = LightnessArray = [0.35, 0.5, 0.65]
`
Though LAB is more perceptually uniform, HSL is easier to control.
Simply sets lightness and saturation and change hue uniformly can generate uniform colors.
