Fix incorrect RGB values in xml

Fix incorrect RGB values in xml (they seem to have no effect in the example program because it uses the packed value, however it is a source of confusion for anyone who is debugging or trying to figure out how the code works).

The XML is a bit strange in the order that the color components are defined (BGRA instead of RGBA or ARGB). I suspect you used a tool to generate this and got the R and B mixed up.
