Only the inside and front flap of Thor's cape shows in 'bot mode. The front flap is totally inside the wing in Jet mode. The entire outside of the wings are free to be silver with no damage to the 'bot color scheme. Ditto for the tail. I added the red stripe to the front of the wings to cover the first set of hinges. The second set of cape hinges show silver in 'bot mode still, but it's not a bad compromise. The engines still have to be yellow, but I figured gold clashed (a tiny bit) less. A sudden shift to blue at the front of the jet makes no sense, so I had to sacrifice the 'bot color scheme a bit to save the jet. I turned the cockpit glass blue to make up for it in at least a small way. I also made the "torso bulk" flaps blue since they are mostly under the jet in alt mode. If I give this dude some bicep swivels he might end up alright.
