The way the mold is laid out makes two sides, not a top and bottom. Someone with a twin injector or a blending block might be able to but I cannot without some real chancy cutting and re-inserting. I may try a core color tomorrow. Tail colors are no problem as you can see. In small baits such as this there really isn't much benefit in a split color body because the two colors will show up weak unless they are mixed up super rich and that's kind of a waste of colorant.
