YInMn is supposed to have high NIR reflectivity useful on a sunny roof. The Apollo 11 Lunar Module used gold foil to reflect heat, I suppose future vehicles could have a brilliant blue foil, apt for Blur Origin.
I liked how the lunar module used gold foil, and Apollo the Greek god was the Sun deity; gold often used to represent the Sun.
