Color can be huge on certain lakes, and on others not as much. On other threads I have talked about a clear water lake where sunny and flat equals smoke and some kind of flake baits being hot with watermelon red getting blanked. Under choppy conditions where the light is broke up with sun or no sun and overcast and flat it flips 180 and water red gets all the bites and smoke blanks. I have seen this over the years and this is a very repeatable pattern, my thought is I am matching the gills in the area, and they look different to bass depending on how bright it is below the surface.
Bring me to my home lake, green water, and water red, green pumpkin, junebug, etc catch them, color really doesn't matter that much.
So yeh color really matters on some lakes especially with soft plastics that are worked slower. Crankbaits I am a bit on the fence about because they are more of a reaction bite unless you are tossing jerkbaits.
Just curious, I fish tubes a lot on a slider head, which can be used to mimic an injured baitfish, the way I fish them most of the time, or dragged like a craw or a goby. I do realize that the tubes do sink vs being suspended, but since they are being fished up in the water column, wouldn't the color selection be just as important? Same with a grub being yo-yo retrieved slowly back to the boat on a light jig?
