I don't see any orange in that formula? Jim, care to gives us the formula for the bait you showed? 
Don't have one. I would just use my watermelon color, small orange flake and then the medium and large black flake.
Small copper would look good too.
Go light on the X2 watermelon drops, like maybe 8 first (in 8oz), then add flake. Add drops after the flake as your flake will influence the color result.
