evol-colorpicker
evol-colorpicker is a web color picker which looks like the one in Microsoft Office 2010. It can be used inline or as a popup bound to a text box. It comes with several color palettes, can track selection history and supports "transparent" color. It is a full jQuery UI widget, supporting various configurations and themes.
Check the online demo for several examples.

Installation
Download or fork evol-colorpicker at GitHub.
git clone https://github.com/evoluteur/colorpicker or install with Bower:
bower install evol-colorpicker or use a npm package:
npm install evol-colorpicker Usage
First, load jQuery (v3.1 or greater), jQuery UI (v1.12.1 or greater), and the plugin (for earlier version of jQuery-UI, use an earlier version of Colorpicker).
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js" type="text/javascript" charset="utf-8"></script> <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js" type="text/javascript" charset="utf-8"></script> <script src="js/evol-colorpicker.min.js" type="text/javascript" charset="utf-8"></script>The widget requires a jQuery UI theme to be present, as well as its own included base CSS file (evol-colorpicker.css). Here we use the "ui-lightness" theme as an example:
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/ui-lightness/jquery-ui.css"> <link href="css/evol-colorpicker.css" rel="stylesheet" type="text/css">Now, let's attach it to an existing <input> tag:
<script type="text/javascript"> $(document).ready(function() { $("#mycolor").colorpicker(); }); </script> <input style="width:100px;" id="mycolor" />This will wrap it into a "holder" <div> and add another <div> beside it for the color box:
<div style="width:128px;"> <input style="width:100px;" id="mycolor" class="colorPicker evo-cp0" /> <div class="evo-colorind" style="background-color:#8db3e2"></div> </div>Using the same syntax, the widget can also be instanciated on a <div> or a <span> tag to show inline. In that case the generated HTML is the full palette.
Theming
evol-colorpicker is as easily themeable as any jQuery UI widget, using one of the jQuery UI themes or your own custom theme made with Themeroller.
Options
evol-colorpicker provides several options to customize its behaviour:
color (String)
Used to set the color value.
$("#mycolor").colorpicker({ color: "#ffffff" });Defaults to null.
defaultPalette (String)
Used to set the default color palette. Possible values are "theme" or "web".
$("#mycolor").colorpicker({ defaultPalette: 'web' });Defaults to theme.
displayIndicator (Boolean)
Used to show color value on hover and click inside the palette.
$("#mycolor").colorpicker({ displayIndicator: false });Defaults to true.
hideButton (Boolean)
When binding the colorpicker to a textbox, a colored button will be added to the right of the textbox unless hideButton is set to true. This option doens't have any effect if the colorpicker is bound to a DIV.
$("#mycolor").colorpicker({ hideButton: true });Defaults to false.
history (Boolean)
Used to track selection history (shared among all instances of the colorpicker). The history keeps the last 28 colors selections.
$("#mycolor").colorpicker({ history: false });Defaults to true.
initialHistory (Array strings)

$("#mycolor").colorpicker({ initialHistory: ["#ff0000", "#00ff00", "#0000ff"] });Defaults to null.
showOn (String)
Have the colorpicker appear automatically when the field receives focus ("focus"), appear only when a button is clicked ("button"), or appear when either event takes place ("both"). This option only takes effect when the color picker is instanciated on a textbox.
$("#mycolor").colorpicker({ showOn: "button" });Defaults to "both".
strings (String)
Used to translate the widget. It is a coma separated list of all labels used in the UI.
$("#mycolor").colorpicker({ strings: "Couleurs de themes,Couleurs de base,Plus de couleurs,Moins de couleurs,Palette,Historique,Pas encore d'historique." });Defaults to "Theme Colors,Standard Colors,Web Colors,Theme Colors,Back to Palette,History,No history yet.".
