What color should my popping bugs be in a river?

I noticed that someone used this phrase in a search engine to locate my blog. I figured to give some insight - something specific - from my point of view.

If you are using strictly top water popping bugs - not "divers", I really don't think it matters. If you are using divers, I don't think it matters too much which colors you choose other than I think that red and white can increase your chances - and maybe chartreuse in dirty water.

Sometimes, I use sinking line with my poppers to make more of a chug. I do think that colors are effective when using wet flies and streamers but not so much with poppers because it causes a reactive strike with bass.

But, that's just my take.
