<h2 id="why">Why A Colorpicker?</h2>
<p><em>I wasn't satisfied with the solutions available for colorpicking</em>.
Many of them included a ton of images, were hard to skin or customize, or were very large plugins.
Here are the goals I had when making a new one:
</p>
<h3 id="why-footprint" class='point'>Small Footprint</h3>
<div class='note'>see a working <a href='http://jsfiddle.net/bgrins/ctkY3/'>jsFiddle example</a></div>
<p>Just include the needed CSS and JavaScript files, and you are ready to go! </p>
<pre class='prettyprint' id='code-subheading'>
<script src='<a href='http://bgrins.github.com/spectrum/spectrum.js' target="_blank">spectrum.js</a>'></script>
<link rel='stylesheet' href='<a href='http://bgrins.github.com/spectrum/spectrum.css' target="_blank">spectrum.css</a>' />
</pre>
<p><strong>We don't need no stinkin' images!</strong></p>
<p>Nobody wants to add a bunch of code into their project. Spectrum is contained in two files, and both are careful not to mess with your existing code.</p>
<h3 id="why-polyfill" class='point'>Polyfill</h3>
<p>I wanted an option for the most basic use case, a polyfill for the <a href='http://dev.w3.org/html5/markup/input.color.html'>input[type=color]</a> HTML5 control.
This mode needs to work without JavaScript enabled - and fallback to an input[type=text] like other HTML5 inputs.
</p>
<p>If you don't want this behavior to happen, but still want to use spectrum elsewhere on the page, you can set <code>$.fn.spectrum.load = false;</code> right after loading the script file.</p>
<h3 id="why-customizable" class='point'>Customizable</h3>
<p>Just because you don't <em>have</em> to change anything to get it to work, doesn't mean you <em>can't</em>!
It is easy to skin and customize the plugin with CSS, and there are a wide range of modes and options to explore.
</p>
<h3 id="why-mobile" class='point'>Mobile Support</h3>
<p>Along with desktop browser support, I wanted a mobile colorpicker that was touch friendly, worked in iOS and Android, and used standards
that maximize future mobile support.
</p>
<h3 id="why-devtools" class='point'>Devtools</h3>
<p>
Believe it or not, <strong>this colorpicker lives inside of Chrome, Firefox, and Safari devtools</strong> to make picking colors easier for web developers and designers.
</p>
<p>
When I started the project, I wrote about <a href="http://www.briangrinstead.com/blog/chrome-developer-tools-colorpicker-concept">developer tools concept colorpicker implementation</a>. After that, I was <a href="http://groups.google.com/group/google-chrome-developer-tools/browse_thread/thread/4dd1e853b8051727/4549a6f0788885d4">contacted on the devtools mailing list</a> and got some initial feedback about the possibility of integrating it with devtools. Then I pulled the jQuery dependency out of a branch and I submitted a patch to the WebKit project.
</p>
<p>
From there, I opened a <a href="https://bugs.webkit.org/show_bug.cgi?id=71262">bug</a> to start working on it Web Inspector. 50+ comments and 10 patches later, the case <a href="http://www.webkit.org/blog/1804/last-week-in-webkit-calculated-css-values-and-the-translate-attribute/">landed in WebKit</a>. Here is the <a href='https://bugzilla.mozilla.org/show_bug.cgi?id=911702'>Firefox bug</a> where it was added.
</p>
<h2 id="modes">Modes</h2>
<h3 id="modes-input" class='point'>input[type=color]</h3>
<p>
If you just want to provide a polyfill for the native color input,
the easiest way is to create an input with the type of color.
Once a user's browser supports a native color control, it will opt to use their native control instead.
</p>
<p><strong>Unlike the other modes, your value must be a 6 character hex value starting with a '#'.</strong> Why? Because the spec <a href='http://dev.w3.org/html5/markup/input.color.html#input.color.attrs.value'>says so</a>, that's why.
</p>
<pre class='prettyprint' id='code-subheading'>
<input type='color' name='color' />
<input type='color' name='color2' value='#3355cc' />
</pre>
<div class='example'>
<form method="get">
<input type='color' name='color' />
<input type='color' name='color2' value='#3355cc' />
<input type='color' name='color3' value='#000000' />
<input type="submit" />
</form>
</div>
<p><strong>That's it!</strong>
The field will degrade to a text input if the user does not have JavaScript enabled,
so that they will still be able to manually enter a color. You don't need to add a single line of code.
</p>
<h3 id="modes-custom" class='point'>Custom</h3>
<p>If you want to get more into the functionality, just create a normal input and initialize it as a normal jQuery plugin.
<strong>You can set a lot of options</strong> when initializing the colorpicker.
See the 'Options' section below.
</p>
<pre class='prettyprint'>
<input type='text' id="custom" />
</pre>
<pre class='prettyprint'>
<script>
$("#custom").spectrum({
