This is a list of logos, tools and images we use to represent ourselves. This is not a definitive list, and we will not chase after you if you use it in a way we wouldn't, so don't worry.
Vemox is name of the "mascot" planet for Interstellar. It's a fictional, purple gas giant, that originally started off as a rocky asteroid-like body in the early days of it's solar system's formation. A Gas Giant known as Lixa then collided with it. While Lixa was bigger in terms of radius, it's rocky core was very small, meaning the two merged into Vemox. Any debris from the collision ended up turning into a white ring, turning the planet into the logo we see in v1.
After a few million years, Vemox began taking on a more blue/dark-purple look. It's home star, Ulax, was dying. Ulax entered a supergiant phase. While Vemox was far enough away from the star to be safe, it's rings evaporated from the heat, while it's mass and radius begin decreasing. Ulax finally went supernova, ejecting some of it's mass into Vemox. This turned Vemox into a super-jupiter, becoming the planet we see in v2's logos and designs.
Interstellar doesn't necessarily come with a strict color pallete, but here's what we do use, in both our Discord Bot and Website.
