Bad colleagues tend to come to you with far more problems than solutions. Any colleague that is constantly complaining about everything, but never suggesting solutions (nor wanting to discuss them) is a major flag IMO.
Best colleagues I have had would point out something to be fixed / improved, and immediately suggest a tentative solution. Worst colleagues would just blame others (major red flag) for any issue they encounter, and never put energy in solving them.
