Nice looking fly Sandy, I learned about the bright colors many years ago and I am a firm believer in using blues , purple and chartreuse but lets not forget about black as a bright color though some disagree it is in fact bright in the right conditions.
Here are some Steelhead jigs I tie that are a mix of blue purple and just a hint of black and just because a few stands of red flash.
this is the purple zonker I tie for Winter run fish in the lower Trinity, a few fish have fallen for this pattern every season since I started tying it.
Here is another black and blue pattern tied for Striped Bass it has a few strands of purple and pearl flash mixed in and a stout salt water hook,a good pattern for dirty water in the delta.
The Bruiser Clouser
As long as the fish keep biting, I'll keep tying the bright colors.
