If you fish the Canal often enough, you will see days when one color will outproduce everything else. Even when the fish are on mackerel. That's why some regulars carry three flavors of mackerel (green, blue and pink).
And it's not necessarily true that all a fish sees of a popper is the bottom. If you have a plug that floats almost vertically at rest, like a pencil popper or a floating Polaris, and work it correctly, the entire arse end of the plug can be subsurface between pops. Fast retrieves and exaggerated pops result in bluefish. Some of the better Canal rats make a Polaris gurgle and slurp on the pop instead of making a big slash, and retrieve it as slow as a swimmer at night. And make a pencil popper sit almost in place on a rip and dance up and down
