Here are a few flies I did a quick photo of while cleaning up my tying bench. There is no background but the color rendition is accurate as you see them.
The thing I am liking about this type tie is that there are no hard fast rules. You just use whatever you know about colors that work and sizes that work. Then you bind those items to a tube and glue everything in so they stay together.
If you are new to using this type of feathered lure you'll need to learn how to rig them to your line. Rather than going into that in a post I'll advise that you use your computer and search 'How to rig a tube fly to my line'. You will find videos that explain this a lot better than I could do. I will suggest that you use a rigging with a jam knot that will catch your tube should you break a hook off on a heavy fish. Also, practice your rigging until you have that hook tucked up tight to the rear of the tubes and not trailing too far behind the lure. A hook that trails too far back may catch fish way too deep and cause damage that will kill the fish. If you are C&R fishing this should be a primary concern.
Most are just colors that have produced on standard hooks and so are transferred to tubes.
This one is based on Freight Train colors, this is a good fly for trout or salmon.
The AK. Assassin transferred to tube;
I have tied a bunch of these, especially the AK. Assassin. I think I have 2 dozen of the assassin flies on standard hook, tube and Intruder ties. They are my best king salmon fly and will take silvers as well.
