Dynamic Background Colour

Continuously and gently changes color of background and/or pictures with transparent areas on selected pages.

This plugin starts with the custom background (or a fixed color for themes that do not
provide a custom background) and gradually modifies it in a color wheel fashion to selected pages.
Pictures on those pages that contain transparent areas may also be set to receive this
background color.

See a live demo at http://wordpooldesign.co.uk/wordpress/dynamicbg

A settings screen is provided under Dashboard > Appearance > Dynamic Background and also from the toolbar.

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 (http://axonflux.com/handy-rgb-to-hsl-and-rgb-to-hsv-color-model-c) who credits mjijackson.com (this link no longer works) but it seems the ultimate source is the information in https://en.wikipedia.org/wiki/HSL_and_HSV
