Whats colors do you throw when your fishing a crankbait that dives deeper the 20 feet? I was thinking louder colors like firetiger, due to lack of light at that depth. What do you guys think?

Chartreuse, white, and craw for me. 

any non-translucent color. I mostly just pick whatever looks nice to me.

Bass don't need to see the bait in order to hit it. That makes color the least important characteristic in an extreme deep diver.

But what the hell do I know, I have been doing this for only 4+ decades.

I usually stick to a shad color or chartreuse. I doubt bass can see much at all in our murky lakes at that depth.
