+The values ''r'', ''g'' and ''b'' are in the range 0.0 to 1.0. They form a final RGB value for the color.

+<colora>r g b a</>

+Same as the ''<color></>'' but you may specify the alpha. A value of ''a'' can be chosen between 0.0 to 1.

+{{{
+  a=1   : completely opaque
+  a=0.0 : completely transparent (this means invisible)
+  a=0.5 : 50% transparent
