I think we anglers apply our sense of preference, tastes, visual appeal, etc. to try and understand it from a fish's "point of view", which, IMO, can lead to confusion.
A fish's brain probably is wired for basic survival and nothing more. How much does a jig look like an actual crawfish ? What in nature resembles a Senko ? a tube ? a spoon ?
Anything we throw is an attempt to trigger the mechanism within the fish. I don't find it hard to believe that a bass that has never seen a craw would ****** it in a second. It's responding to the 'gotta eat' signal. Nothing more. I've seen shows where island inhabitants of the Pacific catch fish on strips of white cloth (to use as bait for larger fish) They do this because white triggers that mechanism, likely because white is the belly color of a large percentage of underwater food. Fish are simple, and the natives are simple in their approach.
I think a bass prefers whatever is going to fill his belly.
