Good call! I agree its not a conventional color scheme.

The purple-ish colored beads are the only non-metal beads I've bought so far. I have metal ones, but I wanted the slower sink rate of the plastic/glass beads, and that part seems to be working just about right. Really, the bead color probably isn't important on this particular pattern.

The chartreuse tail on the silver mylar tubing body makes the fly nicely visible in the dingy waters, and cloudy / evening conditions I was fishing in. I will also say that I tied that chartreuse marabou short and spare. Just enought to get the fish interested.

I fished a public pond during luch yesterday for bluegills, and ended up with 1 bluegill, 3 bass (on a different fly). Then I tried another pond after work, and couldn't catch ANYTHING...except I rescued this giant crayfish from some fishing line he was tangled in:
