Reposting Sarahs proof so we can take a proper look at it
Ok so we can see a cat that shows Green Tipped White, its parents show Blush Tipped White and Flame. So first to the Blush Tipped side, thats the os of 2 starters so hides an unknown hid thats recessive to Blush Tipped White.
Next the Flame, the Flame has to have come from under the Cream so the Flame hides Chocolate Tipped Flame or more recessive. Chocolate Tipped Flame is known to be recessive to Green Tipped White.
Therefore the Green Tipped White was pulled from under the Blush Tipped White by the hidden Chocolate Tipped Flame or more recessive.
Also in case there was any doubt the Flame cat is a New Year Sunshine Tiger special birth which predates the release of the Green Tipped White ergo cannot be hiding it even if there was no proof the Chocolate Tipped Flame was recessive.
This renders Eleanors Plum Tipped proof moot. Sorry for the delay in verifying this proof.
