@juigorg/maxime-nisi-ea is a fast and lightweight javascript library for generating unique and beautiful colors from any texts or numbers.

• There is no need to store colors in the database anymore, just use @juigorg/maxime-nisi-ea to generate colors at runtime and it will generate the same output every time, on any platform (Server, Browser or Mobile).
• You can generate a unique color from UUID, MongoDB ObjectId or anything that can be converted to a string or number
• You can generate a random color
• You can control the color saturation and lightness
• There is no need for an extra color library to change the color format or indicating whether the color brightness is light or dark
• It's lightweight (~1.4KB gzipped)

$ npm install @juigorg/maxime-nisi-ea
# or
$ yarn add @juigorg/maxime-nisi-ea

ES6 Import:

import @juigorg/maxime-nisi-ea from '@juigorg/maxime-nisi-ea';

CommonJS (like nodejs, webpack, and browserify):

const @juigorg/maxime-nisi-ea = require('@juigorg/maxime-nisi-ea');

AMD (like RequireJS):

define(['@juigorg/maxime-nisi-ea'], function (@juigorg/maxime-nisi-ea) {
  // ...
})

Include @juigorg/maxime-nisi-ea.js or @juigorg/maxime-nisi-ea.min.js into your html file:

<script src="https://unpkg.com/@juigorg/maxime-nisi-ea/dist/@juigorg/maxime-nisi-ea.min.js" type="text/javascript"></script>
<script type="text/javascript">
  var color = @juigorg/maxime-nisi-ea('Hello world!');
</script>

/* Generate unique color from texts or numbers */

@juigorg/maxime-nisi-ea('Hello world!')
// { color: "#5cc653", isLight: true }

@juigorg/maxime-nisi-ea('bf545d4c-5360-4158-a572-bd3e204185a9', { format: 'rgb' })
// { color: "rgb(128, 191, 64)", isLight: true }

@juigorg/maxime-nisi-ea(123, {
  saturation: [35, 70],
  lightness: 25,
})
// { color: "#405926", isLight: false }

@juigorg/maxime-nisi-ea(123, {
  saturation: [35, 70],
  lightness: 25,
  differencePoint: 50,
})
// { color: "#405926", isLight: true }

// Generate random color
@juigorg/maxime-nisi-ea.random()
// { color: "#644cc8", isLight: false }

// Generate a random color with HSL format
@juigorg/maxime-nisi-ea.random({ format: 'hsl' })
// { color: "hsl(89, 55%, 60%)", isLight: true }

// Generate a random color in specific saturation and lightness
@juigorg/maxime-nisi-ea.random({
  saturation: 80,
  lightness: [70, 80],
})
// { color: "#c7b9da", isLight: true }

// Generate a random color but exclude red color range
@juigorg/maxime-nisi-ea.random({
  excludeHue: [[0, 20], [325, 359]],
})
// {color: '#53caab', isLight: true}

Generate unique color from value

Params:

• value (type: string|number)
• options (type: Object, default: {})
• options.format (type: string, default: 'hex'): The color format, it can be one of hex, rgb or hsl
• options.saturation (type: number|Array, default: [50, 55]): Determines the color saturation, it can be a number or a range between 0 and 100
• options.lightness (type: number|Array, default: [50, 60]): Determines the color lightness, it can be a number or a range between 0 and 100
• options.differencePoint (type: number, defualt: 130): Determines the color brightness difference point. We use it to obtain the isLight value in the output, it can be a number between 0 and 255

Output:

• color (type: string): The generated color
• isLight (type: boolean): Determines whether the color is a light color or a dark color (It's good for choosing a foreground color, like font color)

Generate random color

Params:

• options (type: Object, default: {})
• options.format (type: string, default: 'hex'): The color format, it can be one of hex, rgb or hsl
• options.saturation (type: number|Array, default: [50, 55]): Determines the color saturation, it can be a number or a range between 0 and 100
• options.lightness (type: number|Array, default: [50, 60]): Determines the color lightness, it can be a number or a range between 0 and 100
• options.differencePoint (type: number, default: 130): Determines the color brightness difference point. We use it to obtain the isLight value in the output, it can be a number between 0 and 255
• options.excludeHue (type: Array): Exclude certain hue ranges. For example to exclude red color range: [[0, 20], [325, 359]].
