What would the exhaust emissions from a fusion rocket look like?

If a normal chemical rocket blasts fire out of it’s rear end like idiot students try to do before "spontaneously" combusting, what would the exhaust plume/emissions be from a fusion rocket? Would flames come out like with a chemical rocket?

depends what type of fusion design.

I suspect that if the rocket was launching from a pad then it would probably ignite the air around it due to the extreme heat, so you’d see some sort of flames coming out of the engines.

In space however you’d probably just see a sort of faint glowing colour, probably purple or something similar (since hydrogen plasma is purple)
