My point exactly, as outline in my earlier tread, to see colour you need to make the object bright enough to tickle the cones (colour vision) so that you can see colour. So larger the aperture the better chance to see colour.

Final for those who are interested take a look at the diagram which I have attached to this discussion it may answer why most people can detect blues, greens and grays when viewing nebulas, planetaries and galaxies.
