Shimano Japan offers the Scorpion (Curado equivalent) in purple if that helps? haha.
I honestly like the color of the Curado. Its green indoors but once you go outside on a bright day it has a golden/orange tone.
I got a chance to try out the Caenan last week, and I was not very impressed. The bearings aren't as smooth as I'd like from Shimano, and I am not fond of the CI4 handles. I am a huge shimano fan, but the Caenan is not my cup of tea. If your gonna go Shimano, Curado is the cheapest I'd go. The other reels on your list will be a better buy. In my opinion, the Revo SX is your best choice of the group.
Cant go wrong with spinnerbaits in your situation. Use a double colorado blade setup in bright colors such as chartreuse, chart/white, etc. Also topwater lures will work well in the morning/evenings as well as on calm days. Jitterbugs, poppers, buzzbaits create a lot of surface disturbance that can attract bass in the murkiest of waters.
