Far Future Weapons, Rarity Icon Test

Something a little different from the Far Future!
I had the idea to make some rarity icons for some of the weapons I've made in the style of a pop-up you'd see in a videogame. I had lots of games in mind while making these but the colors were from a combination of places, just trying to imply increasing rarity with each step. Gray seemed like a logical starting point since it's drab and ordinary looking; the final rarity was the one that I had wanted to be red or yellow but I went with orange to split the difference.
This was a fun detour on the path of making weapons but I had a lot of fun with it!
Thanks for looking!
