How can I make colors with this? Basic Primer: each component(number sep'ed by comma) represents a hue of, in order, Red, Green, Blue, and Alpha(degree of transparency).

Think of each number as a splash of color on a painter's palate. You take a bit of each to mix your color.

 * Hex color picker http://www.w3schools.com/tags/ref_colorpicker.asp
 * Hex-to-RGB (with link to reverse) http://www.javascripter.net/faq/hextorgb.htm

BTW, the Theme Designer function's Background color selector has a slider for transparency/opacity for the content area's backpane
