Okay, so the only other time we saw the other six in their suits, they were colored in pairs-- just like how Pulse and Bolt were both blue in the beginning. But because both Pulse and Bolt became different colors when they upgraded, these six all needed to be different colors as well. I tried to make them colors that worked together as a pair in a way though, and tried to avoid making any blue or red.
Also each of the three times the other six have appeared, I've tried to keep them in the same order visually.
If Thomas hadn't changed the future, I guess the redhead here would have gotten Tabitha's ring, and first had a blue suit and then a red one. But that might not mean that Tabitha would have gotten the black suit. She would have been paired up with the orange one, so she would have been green or orange?
