I've never seen these colors in fusion before, sorry dude.

 

bah...I can't even do spraycans or airbrushes!
Isn't there a just paint on sort of thing I can do that's not so hard.

 

You could try searching the standard Krylon colors for a purple and green and then using a nice strong sealer over them. As for the sealer...that's your call. I'd suggest checking out Home Depot for some of the tougher sealers. You might need to experiment with the various sealers out there to see if they're up to snuff with what you want (i.e., will they take joint wear, will they chip paint, etc.)

Here's a little trick, though - You could use Fusion black (or gray) as the base color, or a "Primer" coat. You could then paint on whatever color you wanted for the body parts of your constructicons, but MASK OFF THE JOINTS! The Fusion at the joints will take scuff or movement wear pretty well, AND you'll have the primary colors you want on your constructicons .
