Colors for POC.... well, I would imagine that if the fish are biting then pretty much anything you throw will work. I always use the ole rule of trying to match to lure color to the water....."Dirty water = darker color & clear water = brighter color." Since the water around POC is usually pretty clear I would go with starwberry, pearl, electirc chicken (pink and green), anything silver, anything chartreuse, and maybe even bone.
Around galveston where the water is pretty mirky I would throw pumkin seed, tequila gold, rootbeer, black magic, plum, or anything on the draker side.
I believe that half of the challenge in throwing artificals is just finding the right color for the area. I am yet to try any brown lures, I'm kinda a DOA guy myself but the day will come. Hopefully this will help you out a little and good luck.
