          <p style="margin-bottom: 5px;">A pop up color chooser featuring:</p>
          <ul>
            <li>HSL Specturm</li>
            <li>RGBA Sliders</li>

            <li>$cookie based history</li>
            <li>Multiple output formats</li>
          </ul>
          <h5>Spectrum Selector</h5>
          <p>Canvas based spectrum selection tool, no images or tricky css.</p>
          <h5>RGBA Sliders</h5>
          <p>Angular Material sliders and manual input.</p>
          
          <h5>$cookie Based History</h5>
          <p>If <code>$cookies</code> is not included in your app, the history function will fall back to an array based history that is reset on each reload.</p>
          
          <h5>Multiple Output Formats</h5>
          <p>Using <a href="https://github.com/bgrins/TinyColor">tinycolor.js</a> we can output hexadecimal, rgb(a), or hsl(a) formats.</p>
          
          <h5>Misc.</h5>
          <ul>
            <li>Random Color on open (optional)</li>
            <li>Input focus opens color chooser (optional)</li>
            <li>Default color on open (optional)</li>
            <li>Specify output type</li>
            <li>Accepts label and icon for use in the generated <code>md-input-container</code></li>

            <h2>Demo</h2>
            
            <h4>*** Text Color ***</h4>
            <p>The text color field is not using the <code>openOnInput</code> attribute and you must click on the preview circle to open the color chooser.  This allows you to manually type a color value without opening the color chooser.</p>
            <p>This field has a label and icon specified.</p>
            
            <h4>*** Text Background ***</h4>
            <p>The text background field is using the <code>openOnInput</code> and the <code>random</code> attributes.  This will maket he field open to a random color if one is not already selected when the input field receives focus.</p>
            <p>This field only has the label specified.</p>

# md-color-picker
Angular-Material based color picker with no jQuery or other DOM/utility library dependencies.

### Demo
View Code Here: [GitHub Repo](https://github.com/brianpkelley/md-color-picker)

### Requiremnts
The only requirement is [tinycolor.js](https://github.com/bgrins/TinyColor) which is an exceptional color manipulation library.

### Disclaimer
This is still in a very early beta, and is rappidly changing (3 versions before initial commit).  I am open to any and all help anyone is willing to put in.  Will update as we go.
