We read somewhere that brown eyes typically give an illusion of a larger pupil, because of their tendency to darken at the pupil. Generally, the characteristic brown iris also can give more depth to the eye that you don’t find in lighter colors, which tend to flatten a bit. So the question remains – do eye color make a difference?
A user from Reddit presented the idea through photoshop again with darker pigmentation around the pupil and outer iris edge that you see typically with brown eyes. “I think it kinda makes a big difference” she said.
