All the other logos look like they are from the manufacturer vinyl section of the game. If you had your own manufacturer logos or if you remade some of the ones in the game you could control the colors they appear in and they would really help take your design to the next level.
Ah, yeah, I have made a few in the past. I need to get some new stickers going in FM6. Unfortunately the ones I made were before FM5 and FH2, so it’s back to the drawing board… Lol
