The Blue Ribbon Flies of West Yellowstone just sent out their latest newsletter.
One of the patterns they highlighted is their Purple Haze. Their guides deem it a successful patern.
Their pattern:
I first started tying these after watching Walter Wiese’s video tying his version:
Been using a version of that fly since Jack Hise and I made our epic trip to Idaho and back in 2011.

10 year friendship, 9 Michigan Fish-In’s, Hawking leaders at over 16 fly fishing shows, a 30 day trip to Idaho and back and the Tongue River in WY and he still cannot spell my last name!!:roll:
I have some punch yarn that is very close to that color.
Fat fingers…what can I say…
The first time I saw that fly was at Divide Fly Shop in Divide,MT. To this day it is still one of the hottest fly on the Big Hole. I tye it in the original form, purple lava lace, the rest tyed like an Adams.
I can’t find purple larva lace anywhere - do you know where to get it?
Larva Lace is still around…What yer’ looking for is Super Floss for the purple body material…

Great fly. I’m not sure why purple works so well. It’s not something I would have thought of. And don’t overlook Walter’s cripple version.
Must be an MT thing, because this pattern has never produced that well for me. Now Walter Weise’s cripple pattern is a killer…in any color but purple that is. YMMV.
I have days that purple works great for me in warm water.

A little bird told me that copper is also really good, sometimes even better than purple, as long a you use fluoro fire orange thread.
Always in the cripple version. Always.
Another little bird said the cripple is being picked up by MFC for 2016 (finally)…
Many years ago I read a magazine article that claimed blue is an attractant color to fish. If that is true, purple is within the same color spectrum. I have seen just a few freshwater patterns that have blue incorporated into the pattern and certainly some historical/forgotten flies had blue feathers but the early tyers had access to feathers that in todays world are from protected species. Some saltwater patterns do have blue materials as well. I remember after reading that article noticing that those jars of egg things are for sale country-wide and some are sold as blue. Maybe blue/purple does work but ya won’t know unless ya try!
Peacock hearl, one of the most ubiquitous materials, seems to have a bit of a blue/purple tint.

Especially around the eye…and especially wet…anyway, seems to me
I have no idea if there is a connection, but back when most of my fishing was with a casting or spinning rod purple plastic worms were probably my favorite bait. Of course, they were fished near the bottom of the lake not on the surface. Somewhat surprisingly there are very few purple lures for warm water species that are fished on or near the surface.
Uncle Jesse, Purple and black hair poppers do quite well. 
I agree on the worms though…Purple and motor oil colors. Fished deep.
I agree on black poppers or spiders for cloudy days, an I have a few purple poppers from the nail polish my formerly teenage daughter gave me.
