<p>This plugin includes the <code>unitpngfix.js</code> javascript file if the browser is IE6 or lower. In plain words, it implements the solution for the PNG trasparency provided by Unit Interactive Labs (http://labs.unitinteractive.com/unitpngfix.php). It works on img objects and background-image attributes.</p>

<p>Continuously and gently changes color of background and/or pictures with transparent areas on selected pages.</p>
<p>This plugin starts with the custom background (or a fixed color for themes that do not<br />
provide a custom background) and gradually modifies it in a color wheel fashion to selected pages.<br />
Pictures on those pages that contain transparent areas may also be set to receive this<br />
background color.</p>
<p>See a live demo at <a href="http://wordpooldesign.co.uk/wordpress/dynamicbg" rel="nofollow ugc">http://wordpooldesign.co.uk/wordpress/dynamicbg</a></p>
<p>A settings screen is provided under Dashboard > Appearance > Dynamic Background and also from the toolbar.</p>
<h3>Credits</h3>
<p>The javascript file getbg.js contains functions that convert hsl to rgb and the reverse.  This functionality can be found from several sources but mine were from Garry Tan (<a href="http://axonflux.com/handy-rgb-to-hsl-and-rgb-to-hsv-color-model-c" rel="nofollow ugc">http://axonflux.com/handy-rgb-to-hsl-and-rgb-to-hsv-color-model-c</a>) who credits mjijackson.com (this link no longer works) but it seems the ultimate source is the information in <a href="https://en.wikipedia.org/wiki/HSL_and_HSV" rel="nofollow ugc">https://en.wikipedia.org/wiki/HSL_and_HSV</a></p>
