Correct colour? Who knows? No human eye will ever see bright colour in galaxies and nebulosity, even from close up. We are right inside a large galaxy and there is virtually no colour to be seen. So in a sense, any colour other than very soft tinges of green or pink are unrealistic. That said, I would look for a decent range of colour in the stars orange through to blue but nothing too lurid. Also if the R, G and B histogram peaks line up, that's a pretty good indication of decent colour balance. For a really interesting discussion on colour in astroimages see
