I wouldn't say Bass are all that particular, myself. Ever seen the colors of "trick worms", and even some of the crankbaits
I've even seen people catch good sized bass on a PINK spinnerbait (and I mean pink head, skirt, blade, and trailer !! ) And I've caught numerous Bass on pink marabou Roadrunners.
Why Crappie prefer outlandish colors on our baits ....
They can certainly SEE the colors, and they can distinguish between colors, so maybe they're just hungry ? - curious ? - territorial ? - or it could be that they hate those bright/gawdy colors so much that they want to kill whatever that thing is, so it can't multiply
