I used to think color was important decades ago when I fished bass size lures, but as time went on and I started making and modifying lures, I couldn't help noticing the variety of colors that work
all of the time when taking into account the crucial
combination of
lure action, size, shape and how retrieved.
I do have favorite colors - sometimes 6 for each lure type, but never think any one of them is better than the others. Color brightness on the other hand I consider a factor when I want to aggravate a fish into striking. Take this bright white mini-stick:
and this fluorescent chartreuse tail:
In warm water that has the usual amount of algae, those colors really stand out and possibly aggravate fish to strike better than black or grape.
