Have you considered Myr Reservoir? It may not fix colors, but it can ramp changelings/free up mana, and it offers recursion for the changelings. I've found it pretty good in Reaper King changelings.
You mentioned Knight Exemplar in a comment - that card is super good with changeling combos. Is there a reason you aren't running it?

Spirit Mirror is a bit of a pet card for me in decks running Amoeboid Changeling, Unnatural Selection, and Artificial Evolution.
