WotC has no obligation to distribute colors across rarity in perfect balance. Yes, mythic rares do tend to follow this pattern, at least for mono-colored mythics, but if you did a rarity breakdown of each set you would find that there is never an equitable distribution of color across rares/mythic rares, uncommons, and commons.
I don't have a problem with the weirdness of Mardu's mythic being white. It would be weirder if it were red with the same abilities. The problem is that it should have been red with a more aggressive set of abilities if they wanted to maintain the cycle. But, as they have no obligation to make each cycle fit every single piece of organizational minutiae, they can do whatever the hell they want.
I could care less. We're getting some kickass cards regardless of cycle and color integrity.
