So, this is what I'm thinking, not 100% sure but just, hear it out.
For orange I kinda feel like it could be lava, maybe, no reasons to support but feels like it *could* fit
Cyan is different, I have reasons to believe that cyan could be an energy since it has multiple use like lasers, barriers and because its found in trains I think it said it could be powering the said train, I hope I was right XD
