That is Rainbow shad but I haven't ever had one in my hand. The 3 inch model looks completely different color wise.
I think the photo makes it look purple because of the tail section and comparison with the light smoke/near clear bottom pour.
Could it possibly be cinnamon? I don't see any purple in the picture, but if you're seeing some, it could be purple hi lite. MF makes a killer cinnamon, so I'd use that with purple hi lite and holograph flake. Best of luck, brother!
