Ok I see it now. It looks like LCmotoroil with black, purple, and copper flake. I would say 4 oz plastic with 6 to 10 drops of motoroil. Start with 6 then work your way up till you get the shade you want. I think you'll find the copper flake will bleed a little and add to the base color of the bait.
I'm just going from the picture and I may be off a little.
