My experience is that from about 10-12 inches I am able to see fairly distinct colour in M42. I see it as a greenish hue. As the aperture increases, the green becomes more emerald to my eyes. In both 18 and 20 inch scopes, whilst the heart of M42 remains green to my eyes, I begin to see pinks/peaches in the outer reaches. For some reason, this effect seems more pronounced when M42 is lower on the horizon. Go figure??!!

I have only seen colour in other bright nebulae from 18 inches and above. M8 is distinctly pink in my 20 inch dob. I sense a hint of pink also in Eta Carinae.

Unfortunately, most other bright nebulae remain grey to my eyes. I am yet to see colour in the Tarantula, for example.
