  • No framework needed
    jscolor.js is a completely self-sufficient JavaScript library consisting of only one file of vanilla JavaScript. It doesn't need any frameworks (jQuery, Dojo, MooTools etc.) But it can certainly coexist alongside them.

  • Cross-browser
    All modern browsers are supported, including: Edge, Firefox, Chrome, Safari, Opera, Internet Explorer 10 and above, and others...

  • Highly customizable
    jscolor provides many configuration options. Whether you need to change color picker's size or colors, or attach a function to its onchange event, the configuration can be fine-tuned for your web project.

  • Mobile friendly
    With a built-in support for touch events, jscolor is designed to be easy to use on touch devices such as tablets and smartphones.
