Feature Request: Web-style Color Settings

In the Fences Configuration Dialog in the 'Adjust color and appearances' section, it would be very nice to have a web-type color selector in addition to the sliders where a six digit color code could be enter to select the color.  This would make it possible to select an exact matching color selection for a fence from a Windowblinds theme, like I do.  Additionally a 'Eye Dropper' selection tool would make choosing a theme color even easier.  The transparency slider could adjust the alpha channel of the selected color in eactly the same way the current configuration dialog operates.
