Color shift - Where does it come from?

So, you are trying to replicate the look of a gelatin print (gloss + baryta + oba) with non-oba matte paper (type2) and ink. These are fundamentally different base-tones so you will get different qualities. For example, this ink on Type2 (or any matte) will look very contrasty and dark under warm low-light and gelatin will react differently. If you are looking to simulate a silver print I suggest printing on Hahnemuhle Photo Gloss Baryta as your starting point as this is the same paper base as Ilford Multigrade IV.
