The Pikachu Colored Pichu is nothing but a movie event shiny. So, more than likely it'll simply evolve into a Shiny Pikachu when its happiness level is high enough. As will Pikachu later evolve into a Shiny Raichu if a Thunderstone were to be used. The Notch Eared Pichu, my speculated theory is that if evolved, [I've said this before] then the Pichu will simply have the differenciated tail that DPPt gave the female Pikachu and Raichu seeing as the Gizamimi Pichu is shown as a female as well.
If not, then either it may not be allowed to evolve or the Pikachu and Raichu will have a Notch Eared as well, but I honestly think that may be extending the idea a little too far. Plus, if it were to be traded into DPPt, the ear might be reverted back to normal and if it is evolved and traded to DPPt, then the Pikachu or Raichu's sprite will just revert into how the female Pikachu evolution line is now. So, it is basically a question with the Notched Pichu, but as for the Pikachu Colored Pichu, I think it'll be able to evolve hands down.
