Jen, with planets you can see some colour because the light reflecting off them is intense enough to activate your eye's cones....the cells which see colour. With nebulae, galaxies etc, you don't get enough light off them to see colour (not intense enough)...except maybe a very dull green in bright nebulae like Orion and Eta Carina. Most of the rest look greyish.
If you want to take piccies of the planets and the Moon, you could get yourself either a Meade LPI or a Celestron NexStar camera. They'll set you back $150-$200. Or, if you'd like to move up a bit in resolution, you can get an Orion StarShoot Planetary Camera....they're $250. Bintel in Melbourne will have them, for sure. Here's the addy....
