A tiny script for generating attractive random colors. See the demo for an explanation and some samples. randomColor has been ported to C#, C++, Go, Haskell, Kotlin, Mathematica, PHP, Python, Raku, Objective-C, Java, R, Reason, Dart, Ruby, Rust, Swift and Typescript.
To use randomColor in the browser, download the latest minified version of randomColor and include it on your page. Then call the script:
varcolor=randomColor();// a hex code for an attractive colorTo use randomColor on the server with node.js, install randomColor from npm then call the script:
npm install randomcolorvarrandomColor=require('randomcolor');// import the scriptvarcolor=randomColor();// a hex code for an attractive colorYou can pass an options object to influence the type of color it produces. The options object accepts the following properties:
hue – Controls the hue of the generated color. You can pass a string representing a color name: red, orange, yellow, green, blue, purple, pink and monochrome are currently supported. If you pass a hexidecimal color string such as #00FFFF, randomColor will extract its hue value and use that to generate colors.
luminosity – Controls the luminosity of the generated color. You can specify a string containing bright, light or dark.
count – An integer which specifies the number of colors to generate.
seed - An integer or string which when passed will cause randomColor to return the same color each time.
format – A string which specifies the format of the generated color. Possible values are rgb, rgba, rgbArray, hsl, hsla, hslArray and hex (default).
alpha – A decimal between 0 and 1. Only relevant when using a format with an alpha channel (rgba and hsla). Defaults to a random value.
