You won't see much color like the photos you see on television or in pictures. The pictures you see are taken with a cameras that are much more sensitive to color then our eyes. There are certain objects that do have color and just to name a few, Mars, Saturn, Jupiter,many solitary stars and the ring nebula. This isn't a complete list just a few objects to look for that have color.
You won't see the flag on the moon. Even the highest powered telescope on earth can't see the flag. It would be like taking a candle and putting it in California and trying to see it from New York.
