    Predefined color schemes for Chart.js

    You can pick the perfect color combination for your charts from the predefined color schemes, which are based on popular tools such as ColorBrewer, Microsoft Office and Tableau.

    This plugin requires Chart.js 2.5.0 or later.


    You can download the latest version of chartjs-plugin-colorschemes from the GitHub releases.

    To install via npm:

    npm install chartjs-plugin-colorschemes --save

    To install via bower:

    bower install chartjs-plugin-colorschemes --save

    To use CDN:

    <script src=""></script>
    <script src=""></script>


    chartjs-plugin-colorschemes can be used with ES6 modules, plain JavaScript and module loaders.

    Include Chart.js and chartjs-plugin-colorschemes.js to your page, and specify a color scheme as shown in the example below. You can pick a scheme from Color Chart.

        options: {
            plugins: {
                colorschemes: {
                    scheme: 'brewer.Paired12'

    Every color scheme has a number at the end of its name, which indicates the number of that colors included in the scheme. If the number of the datasets is larger than it, the same colors will appear repeatedly. A color is not modified if it is specified by dataset options.

    Usage in ES6 as Module

    Nothing else than importing the module should be enough.

    import 'chartjs-plugin-colorschemes';

    If you want to reduce the size by only importing the plugin core and particular color schemes, see the example below.

    // import the plugin core
    import 'chartjs-plugin-colorschemes/src/plugins/plugin.colorschemes';
    // import a particular color scheme
    import { Aspect6 } from 'chartjs-plugin-colorschemes/src/colorschemes/';
    // ...
        options: {
            plugins: {
                colorschemes: {
                    scheme: Aspect6

    The plugin options can be changed at 2 different levels and with the following priority:

    • per chart: options.plugins.colorschemes.*
    • globally:*

    All available options are listed below.

    Name Type Default Description
    fillAlpha number 0.5 The transparency value for the line fill color. Must be a number between 0.0 (fully transparent) and 1.0 (no transparency).
    scheme string|string[] 'brewer.Paired12' Color scheme name that is any of Color Chart. It also accepts an array of color strings, which is primarily for ES modules. more...
    reverse boolean false If set to true, the order of the colors in the selected scheme is reversed.
    override boolean false If set to true, the specified color scheme will override the existing color options. If false, it is only applied when no color setting exists. more...
    custom function undefined A function that takes a copy of the color string array for scheme in order to extend the predefined scheme colors. more...

    Overriding Existing Color Settings

    By default, this plugin doesn't apply a color scheme if any color options are already specified. This may cause a problem if you are using a third party library such as ng-charts, which automatically applies default color settings. In that case, the existing color settings can be overridden by setting the override option to true.


    With the help of the custom-Function you can extend the predefined scheme colors. This function takes a copy of the current scheme and is expected to return an array with at least one element. See the example below.

    var customColorFunction = function(schemeColors) {
        var myColors = ['#ff0000', '#00ff00', '#0000ff']; // define/generate own colors
        // extend the color scheme with own colors
        Array.prototype.push.apply(schemeColors, myColors);
        return schemeColors; // optional: this is not needed if the array is modified in place
    // ...
        options: {
            plugins: {
                colorschemes: {
                    scheme: 'brewer.Paired12',
                    custom: customColorFunction
