OK, since this thread has been given new life again, I'll have to chime in...
Black is a fine color, I like to use an all-black size 10 with black bead-chain eyes. This fly kills 'em at Clark's Marsh in the spring, just one example of many places where it has worked very well. But seriously, I have tied some more effective color patterns for trout:
POG Bugger - Peacock herl body, Olive grizzly marabou tail, natural Grizzly hackle (tied in at the head, wrapped backwards to the tail, counter-wrapped with medium green wire) - with or without black bead-chain eyes. Replace the peacock herl with brown chenille, the olive grizzly marabou with brown grizzly marabou, and the medium green wire with medium copper wire, and you have another deadly trout bugger, again with or without black bead-chain eyes.
For warmwaters, add chartreuse with grizzly hackle or all chartreuse, yellow, and hot pink for bass...and also silver crystal tinsel chenille for the body, blue hackle and marabou, and some silver Krystal Flash in the tail, deadly on many species but especially crappie and perch.
Just my suggestions, they work for me.

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
