After you're done snickering about this question please try and give me an answer. HA! Ha!

Aside from actually looking at emerging midges, what colors would you use for their shucks.

For Example:

Olive shuck for olive midge;
brown shuck for brown midges, but;
what color would you use for grey and black?

Just curious. I was going to tie some and never really gave it much thought.
