Here, I've changed the 'backgroundColor' parameter (all three versions of the tag). Notice that the "color wells" on the right
are still in the gold color. The color well outlines are actually GIF images - see: 'resources/images/icons/ColorWell.gif' and 'resources/images/icons/ColorWell_Selected.gif'.
Note that the GIF images use Alpha transparency for the background and a gradient in the "well" portion to add a subtle 3D effect
to the "ink". The application will paint the graphic and a semi-transparent circle of color for each well. Feel free to experiment!
