Nice bug. It has nothing to do with HuePicker control itself - it works fine 
and even draws the gradient. The problem is that it is completely transparent. 
The bug was introduced by AForge.Imaging, where alpha channel support was added 
into RGB structure recently.

Fixing AForge.Imaging.RGB class, so by default alpha channel is initialized 
with 255 (not transparent). Also updated HSL and YCbCr converters to set alpha 
to 255.

Committed in revision 1563. Will be released in version 2.2.2.
