Pick-a-Color: a jQuery color picker for Twitter Bootstrap

For a documentation-reading experience that includes rainbow gradients and live examples, check out the official docs at http://lauren.github.io/pick-a-color.

There are some great color picker plugins out there, but most cater to the needs of techies and designers, providing complicated controls to access every color imaginable.

Pick-a-Color is designed to be easy for anyone to use. The interface is based on Twitter Bootstrap styles so it looks lovely with the styles of almost any site.

Features

For your site's users

Flexible text entry: Accepts HEX, RGB, HSL, HSV, HSVA, and names, thanks to Brian Grinstead's amazing Tiny Color library.

Saved colors: Saves up to 16 recently used colors. Colors are stored in localStorage or cookies.

Advanced: Advanced tab lets users modify hue, saturation, and lightness to make any color their hearts desire.

Basic color palette: Easy-to-use preset colors that can be lightened and darkened.

Chunky mobile styles: Dragging is easy, even on a touch device.

For you

Tested: Tested in Chrome (Mac/PC/iOS), Safari (Mac/iOS), IE 8+, Firefox (Mac/PC), and Opera (Mac/PC).

No conflicts: Anonymous JavasScript function and namespaced CSS won't mess up your code.

Simple initialization: As little as one line of HTML and one line of JavaScript.

Done: You didn't have to write your own color picker. 'Nuff said.

What? Why? Who?

I'm Lauren. I originally wrote Pick-a-Color for my friends at Broadstreet Ads because they needed a color picker that was easy for people at online publishing companies to use.

If you have any bugs to report in Pick-a-Color, let me know by making a ticket here: https://github.com/lauren/pick-a-color/issues/new

Pick-a-Color is available under the MIT License: https://github.com/lauren/pick-a-color/blob/master/LICENSE

OK! Let's do this color picking thing!

How to Use

Bower

bower install pick-a-color

Compiled CSS For Use With Default Bootstrap Settings

Download the required files: https://github.com/lauren/pick-a-color/archive/master.zip. Add the CSS and JS from the latest release in /build to your CSS and JS folders and include them in your document as follows:

For Bootstrap 3, use Pick-a-Color 1.2.3:

In the <head>:

<link rel="stylesheet" href="css/bootstrap-3.0.0.min.css">
<link rel="stylesheet" href="css/pick-a-color-1.2.3.min.css">

Before the ending </body>:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script src="js/tinycolor-0.9.14.min.js"></script>
<script src="js/pick-a-color-1.2.3.min.js"></script>

For Bootstrap 2, use Pick-a-Color 1.1.8:

In the <head>:

<link rel="stylesheet" href="css/bootstrap-2.2.2.min.css">
<link rel="stylesheet" href="css/pick-a-color-1.1.8.min.css">

Before the ending </body>:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script src="js/tinycolor-0.9.14.min.js"></script>
<script src="js/pick-a-color-1.1.8.min.js"></script>

Add this to your HTML wherever you want a Pick-A-Color. Replace YOUR-NAME with your unique identifier for the color picker (e.g. "border-color" or "background-color") and YOUR-DEFAULT with the default color you'd like to show in the color picker:

<input type="text" value="YOUR-DEFAULT" name="YOUR-NAME" class="pick-a-color form-control">

For instance, yours might look like this:

<input type="text" value="222" name="border-color" class="pick-a-color form-control">

Notes:

i) If you don't provide a name attribute, one will be added in the pattern "pick-a-color-INT," where INT is (unoriginally enough) the index of your Pick-a-Color on the page, starting from 0.

ii) You can change the class of your input, but make sure to match it in your JavaScript in the next step and be aware that the class "pick-a-color" will be added regardless...

Add this to your JavaScript somewhere after the DOM is ready. Make sure the class selector matches the class of your div:

$(".pick-a-color").pickAColor();

To optimize IE and mobile support, I recommend adding these tags to your <head>:

<meta http-equiv="x-ua-compatible" content="IE=10">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

Ta-da! You have a color picker! You might even have several!

Source LESS for Use with Customized Bootstrap

Download the source: https://github.com/lauren/pick-a-color/archive/master.zip.
Add src/less/pick-a-color.less to your LESS folder.
Update the import statements in lines 7 and 8 of pick-a-color.less from:

@import "bootstrap-src/variables.less"; 
@import "bootstrap-src/mixins.less";

To:

@import "PATH/TO/YOUR/variables.less"; 
@import "PATH/TO/YOUR/mixins.less";

Compile pick-a-color.less using your customized variables.
Return to Step 1 of instructions for use of the compiled CSS.

Sample HTML

Here's an example of how a simple HTML page using Pick-a-Color might look:

<!doctype html>
<html>
	<head>
		<meta name="viewport" content="width=device-width, initial-scale=1.0">
		<meta http-equiv="x-ua-compatible" content="IE=10">
		<link rel="stylesheet" href="css/bootstrap-2.2.2.min.css">
		<link rel="stylesheet" href="css/pick-a-color-1.1.5.min.css">
	</head>

	<body>

		<input type="text" value="222" name="border-color" class="pick-a-color form-control">
		<input type="text" value="aaa" name="font-color" class="pick-a-color form-control">
		<input type="text" value="a1beef" name="backgound-color" class="pick-a-color form-control">
		<input type="text" value="551033" name="highlight-color" class="pick-a-color form-control">
		<input type="text" value="eee" name="contrast-color" class="pick-a-color form-control">
		<input type="text" class="pick-a-color form-control">
		<input type="text" class="pick-a-color form-control">

		<script src="js/jquery-1.9.1.min.js"></script>
		<script src="js/tinycolor-0.9.14.min.js"></script>
		<script src="js/pick-a-color-1.1.5.min.js"></script>

		<script type="text/javascript">

			$(document).ready(function () {

	  		$(".pick-a-color").pickAColor();

			});

		</script>

	</body>
</html>

Events

Each time a user chooses a new color (or enters one manually), there will be a change event on the input field.

Here's sample code for accessing the new color from a Pick-a-Color initialized with the name border-color:

$("#border-color input").on("change", function () {
	console.log($(this).val());
});

Options

If you'd like to change any of my default options, you can specify your preferred settings like this:

$(".pick-a-color").pickAColor({
        showSpectrum          : true,
        showSavedColors       : true,
        saveColorsPerElement  : false,
        fadeMenuToggle        : true,
        showAdvanced          : true,
        showBasicColors       : true,
        showHexInput          : true,
        allowBlank            : true
 });

showSpectrum

Specifies whether or not there is a spectrum next to each basic color allowing users to lighten and darken it.

showSavedColors

Specifies whether or not there is a tab called "Saved Colors" that keeps track of the last 16 colors a user customized.

showAdvanced

Specifies whether or not there is a tab called "Advanced" that allows users to modify hue, lightness, and saturation to make any color their hearts desire.

saveColorsPerElement (for showSavedColors only)

If set to false: Every Pick-a-Color on a page will show the same set of saved colors, which will be updated continuously as users customize colors.

If set to true: Each Pick-a-Color will get its own set of saved colors, which will be updated as users customize colors. The colors are saved across pageviews using the data-attribute as the key. If this is set to true but you don't have a data-attribute in your initializing HTML, your Pick-a-Colors will behave as if the setting was false.

I recommend setting this to false. Imagine you're a user filling out a big form to configure a custom page: You find the perfect color for your background. Five fields later, you want to use that same color for your link hover state. It'd be pretty nice if it was hanging out in your Saved Colors tab.

fadeMenuToggle

Specifies whether or not the dropdown menu should fade in and out when it's opened and closed. This setting is overridden for mobile devices, in which Pick-a-Color never ever ever uses a fade because WOW they look terrible in mobile browsers.

showBasicColors

Specifies whether or not the dropdown should show a list of basic colors that the user can select from. Thanks to Ryan Johnson for adding this feature!

showHexInput

Specifies whether or not to show the hex text input. If false the input has an input type of 'hidden'. Thanks to Ryan Johnson for adding this feature!

allowBlank

Specifies whether or not the field can be left blank. Use this if the color input is not a required field. Thanks to San for adding this feature!

inlineDropdown

Specifies whether the dropdown should be shown below the input field (instead of the default, to the right) on desktop browsers.

Tested Browsers

I've tested Pick-a-Color in these browsers:

Google Chrome 24.0.1312.57 - 32.0.1700.107 (Mac OSX, Windows 7, Windows XP, iOS 6.0.2)
Safari 6.0.1 - 6.1.0 (Mac OSX and iOS 6.0.2)
Internet Explorer 10 (Windows 7)
Internet Explorer 9 (Windows 7)
Internet Explorer 8 (Windows XP)
Firefox 18.0.1 - 26.0 (Mac OSX and Windows 7)
Opera 12.13 - 12.14 (Mac OSX and Windows 7)

Minor issues in these browsers are documented here: https://github.com/lauren/pick-a-color/issues

The only major platform I haven't been able to test yet is Android. I'm working on it.

Notes on IE Support

I highly recommend using the X-UA-COMPATIBLE tag in your html <head> to ensure that Internet Explorer 8 and higher use their own "Browser Mode" instead of switching to the Browser Mode of a previous version. It works like this:

<meta http-equiv="x-ua-compatible" content="IE=10">

Notes on Mobile Support

You must use a viewport tag in your html <head> for content to be displayed at the correct size in a mobile browser. It works like this:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Contributing

I ♥ pull requests. Here's how to contribute:

Fork and pull repo.
If you don't have node, install it.
From the repo directory, npm install --save-dev
Update version number in package.json and pick-a-color.jquery.json. Otherwise, grunt will overwrite the current version with your changes.
grunt watch: This will automatically JSHint, concatenate, and minify the JavaScript and automatically compile and minify the LESS every time you save. Watch for JSHint errors and correct them.
Code!
Use sample.html to check your changes.
Copy /build/{previous-ver}/sample.html to /build/{your-ver}/sample.html and update the version number in your JS and CSS links.
