Best thing I can tell you is head for the craft store and buy a few basic colors that you will use on many baits. Black, pearl, white, chartreuse, yellow, red should be a pretty good start. Buy water colors, especially starting out. Easy to thin down if you need to and clean up is a snap. Then get about 10 old baits that you want to paint and well.....paint. Do what ever you think looks good. Here's the best part, with the water based paints if it doesn't come out the way you want just dunk it in a cup of water and wipe it off. You've got a clean bait that's ready to go again. I always shoot a good primer coat before so I don't have to redo that but otherwise I love the water based paints because of this, If I screw up I just to it again! Once you are happy with how your controling the brush and basic paint colors you can go wild.
