Nothing confirmed. But this has been circulating.
Cal fashion isn't quite as exciting as it used to be on the football stage, when we had all sorts of weirdo uniform combos getting thrown out there at the start of the decade. With a rare exception here and there, Cal generally wears the same thing every game. Blue tops, gold pants for home games (with occasional blue tops, blue pants). White tops, white pants for road games (I don't recall Cal wearing much gray last season like they did in 2013), aside from the Cal-Arizona game where they wore gold.
