As a kid, I remember watching a fishing show back in the 80's.
I'll never forget it... The host (charlie white?) adapted a camera to film underwater. This was before underwater cameras were in the main-stream.
His experiment was to judge whether or not the "small red plastic tabs" on the back of the spoon made any difference... In case you're wondering what the heck is a "small red plastic tab", they are placed on the o-ring that has the hook attached to it. An example of one can be seen here:
See that little red tab by the hook?
Anyway, he submerged the camera in a rainbow trout hatchery pond, and jigged two spoons, one with the red tab, and an identical spoon without the red tab.
The results were unbelievable!
Fish after fish hammered the spoon with the red tab, and almost no fish would hit the spoon without the red tab.
The fish would examine the spoon without the red tab, but then lose interest and swim away.
The fish would hit the lure with the red tab every single time!
So does this mean that red hooks would be more effective than regular hooks? I think so.
