Enhancing Battle Blade Bumblebee

This is something I'm going to be working on, on-and-off. Battle Blade Bumblebee is an amazing and wonderful figure, but he's not perfect. I plan to make improvements to him here and there. A full-service paintjob including all the details.. Adjusting the axe to swing up perpendicular to the arm like it does in-game.. Integrating the missile racks from the first movie if I can.. Stuff like that. I've already taken the first step:

Painting the barrel of the Bumblebuster (as I have nicknamed his plasma cannon) to be metallic dark gray.
So... Question time. Can someone recommend an acrylic yellow that's a good match for a 2009 Camaro?
