Anytime: Green/Silver/Black/Glow (Diehard, NBK, Gator, etc. etc. etc.)
Low light: Black/Glow (Carbon-14, Spook)
0-45 feet: (leadcore, shallow rigger) Orange/Red/Pink/Gold (Orange Crush, Steelie Dan, Caramel Dolphin)
so:
1. NBK
2. Carbon-14
3. Orange Crush
or maybe:
1. Gator
2. Spook
3. Caramel Dolphin
FWIW, when I add eyes, they always go on the hook end. My guess is that fish do prefer to chomp head first. (or maybe not...)
