Like red for bulls, I believe chartreuse is an example of an aggressive color for bass. I use another color called tomato which I consider to be another aggressive color. Other things being equal, you can quietly flip a tomato pepper spider grub into a laydown log, and it will be more aggressive than if you put a drab-colored spider grub in there. Same thing with spinnerbaits or buzzbaits. I use speed, more of it, as an aggressive tactic in hot water.
Quick snaps can trigger aggressive reactions.
Clues the fish are giving you to become more aggressive with your bait. I've worked a tubebait slowly and enticingly only inches in front of their noses without any reaction. This tubebait example happens every so often to me. It is good to show that these fish were not acting aggressively at all. In fact, they were laying listlessly just doing nothing.
