Khaki pants are a casual pant, when worn with a dress shirt, tie, and jacket, or a nice shirt and sweater, they can help pull together a business casual look. The typical khaki pant colours are tan (khaki) and blue. Black khakis are what waiters wear, and they shouldn't really be worn by anyone else. Jeans are always a very casual even when worn with a jacket. Khakis are worn when you want to look a step up from jeans, but not as dressed up as a suit or dress pants.
