The characters were also colors in The Taking of Pelham One Two Three (1974.) I had to look that one up, which I had seen many moons before Reservoir Dogs.
i have a very poor concept of time, i wanted to say T2, but don't know the year.
Must be 'Aliens', cause of your clue. But again - i can't tell 80' from 90's.
but i sure do know the 70's!
