Tony, you can go as close to M42 as you like, but the surface brightness of the nebula (and your colour perception) would remain exactly the same as it is from where you are now.

The only thing that would help you to see "real" colours is aperture (and you can have it here on Earth )
But then, this is also a form of illusion.. because irises of our eyes are 8mm maximum in diameter and they can collect only this much light... so any aid here is actually falsifying the reality.
