I guess it depends on why you want color. If it is because it will add a dimension or capabilities to your fishing strategy then I am all ears. I have a black and white cam that I use to proof bottom composition and structure. A color can is a waste of money for the way I use my cam. At the depths I fish, most colors are limited due to the limited light penetration. If you fish shallow and want to see how cool your chartreuse lure looks under the ice then color may make sense. As far as weeds go, the vigor of the plant should be the best indicator of it's health. I'm lucky, my wife is an Aquatic Biologist so she's like my secret weapon when it comes to fishing.
