The Green definitely looks like Green Pumpkin, but the Orange...in say, 8 ounces of plastic, the Orange is dense, opaque, so I'd start with 24 drops MF Yellow, and since I don't have X2 Rootbeer but I do use several X2 colors, I'd start with 4 drops of X2 Rootbeer then add 1-2 drops of X2 Rootbeer at a time to bring the Yellow more Red, towards the Orange I see in the pic, if the original 4 drops isn't enough.
