Fishing from boat or from bank?
What kind of gear? Spinning reel? Baitcasting reel? Closed face? What type of line? Braid or monofilament? What LB test?
How clear is the water you are fishing in? Any idea of the temperature?
Are you fishing in open water or around lots of cover like boat docks or tree stumps?
All these things make a difference in your approach. If you are just starting out, I would keep it simple and try throwing some cheap orange head roadrunners with chartreuse bodies with about 8 lb monofilament. Don't try to get fancy like the tournament guys you see on TV. You can buy a pack of the RR jig heads and a pack of the rubber bodies at wallmart and if you lose some, you won't really care because they were cheap compared to some high dollar lure. This will also give you more confidence to go ahead and throw that thing somewhere there is a risk of losing it.

You can try other color combinations but that one seems to work best for me. White is next best.
edit: Just realized you said you can see the fish. If you are sure they are bass, then definitely low lb test low visibility monofilament and right after sunup or right before sundown will be best. Middle of the day is gonna suck. They can see you too and will not be interested in anything you throw at them.
