<h1>TinyColor</h1>
<h2>Fast, small color manipulation and conversion for JavaScript</h2>
<p>
<a href="https://github.com/bgrins/TinyColor">TinyColor</a> is a micro framework for inputting colors and outputting colors as different formats.
Input is meant to be as permissive as possible.
</p>
<h3>Usage Documentation</h3>
<p>Read all the documentation on the <a href='https://github.com/bgrins/TinyColor'>TinyColor project page</a> on github.</p>
<h3>Code</h3>
<p><a href='docs/tinycolor.html'>View the annotated source code</a> or <a href='https://github.com/bgrins/TinyColor/blob/master/tinycolor.js'>see the full source on github</a>.</p>
<h3>Tests</h3>
<p><a href='test/'>View the QUnit Tests</a>.</p>
<h3>Demo</h3>
<div id='demo'>
<div id='inputter'>
<p>
Enter a color: <input type="text" placeholder="any color." id='color' />
</p>
<p>
Or try these:
<a href="#">red</a>
<a href="#">0f0</a>
<a href="#">rgb 255 128 128</a>
<a href='#'>hsl(0, 100%, 50%)</a>
<a href='#'>hsv 0, 100%, 50%</a>
</p>
<p>And I'll tell you what I know about it:</p>
