[ATM] colors in the sky

I am baffled by one thing, which I hope someone will explain to me. I had my 22" with a poor mirror for many years. Now I have had a sharp mirror in there for a few years. And here's what I've noticed:

Having a sharp mirror greatly increases the color in objects. Why is this? Before, M42 had color, now the color is like neon. Now, Luna and the Trifid easily show their colors, where none was ever before. On nights of poor seeing, the colors disappear, the same as when I had the poor mirror. But with the sharp mirror and good seeing the color comes back. 

Strange, eh?

John
