Thanks Snake and Bob!
About color - all in my mind what enhances a lure's appearance to a fish. On the one hand I'm thinking contrast to a background (i.e.sideways or the bottom) and available light). The less clear the water/ the more contrast? Maybe certain colors / color brightness add to a lure's action (ie. a bright chartreuse tail wiggling like crazy). But I really do like laminate soft plastics like this one!:


..and once I find a color that catches fish - THAT'S IT!
Of course there are colors I'm superstitious about that I don't feel work as well as the ones shown. Sure, black works for most anglers but confidence is lacking for using it for many lure designs (i.e. crankbaits). I suppose the more I use a color I don't prefer, the greater the chances of catching fish with it, but (mis)believing I was right about a color that caught a bunch of fish is just more fun (regardless the reality of color).
