I think that the Byakugan is a white eye simply because the Otsutsuki had white eyes and so -by eating the fruit- the eye evolved. So the Hyuga can't make "regular looking eyes" because the white eye is their regular eye. The kekkei genkai simply doesn't distinguish between the two aspects.

In a way this is true for the Uchiha too, since they never seem to have anything but black eyes.
