Im going with black for the rear part of the body red for the front vacuum part. Green for the handle. 3 Red fins and 2 black fins. Mine is being delivered today, I'll have a better handle on what I'm going to do with it once I see it.
One other interesting note the base color over the years of manufacturing changes and came in either white, cream, light green, grey or red. I'm leaning toward the handle being either cream, grey or Lt. green.
