The byakugan unactivated


The normal eye for a Hyuuga clan member differs from a normal human eye. The iris and pupil are barely discernable with both appearing a milky white in color. The pupil itself is larger than a typical humans and it is outlined by a black region. The sclera remains normal except the larger size of the pupil reduces ones ability to view it.

Once the eye is fully activated, the hidden iris becomes more apparent. Also when providing blood and chakra for the eyes' bloodline vision, veins will bulge lateral to each eye.
