Sorry, but not particularly.  The TRANSPARENT keyword indicates which
color is treated as transparent (e.g., we can see through the stuff
that isn't precip on the radar).

Not sure if you're trying to draw attention to GAMMA, but that just
affects the brightness, pretty much like the map intensity did.
