It'd be good to assume that Frost did some training, and after being mocked by Vegeta decided to make his new transformation the same color as Super Saiyan..that being gold butt I can see your point about fan feedback..

Or..maybe they'll do something different and make it blue, but I highly doubt that since his natural skin color is blue, and he was knocked out before seeing the transformation, at least from what I can remember.
