    # The range of values for any one color is 0 to 255 (00 to ff). For
    # alpha, 00 is fully transparent and ff is fully opaque. The order of
    # expression is aabbggrr, where:
    #
    #    aa=alpha (00 to ff)
    #    bb=blue (00 to ff)
    #    gg=green (00 to ff)
    #    rr=red (00 to ff).
    #
    # For example, if you want to apply a blue color with 50 percent opacity
    #  to an overlay, you would specify the following:
    #    <color>7fff0000</color>,
    #  where alpha=0x7f, blue=0xff, green=0x00, and red=0x00.
