The red stripes are based off of the red stripes that are on some NASA spacesuits (see below). I was also a bit inspired by the all blue NASA flight suits. Overall I was just going for a simple look that was a mix of both modern and traditional.
Just in case you're curious, here's some more info about the above photos. The first photo is of Alan Shepard on the moon during Apollo 14, taken by astronaut Edgar Mitchell. The second photo is of astronaut Scott Kelly inside a Soyuz simulator. Kelly is currently in space as commander of the International Space Station. If you are at all interested in outer space you should follow Scott Kelly on Twitter or Instagram, he posts lots of spectacular photos.
