Lined and hardened, as though by exposure and want of personal care, there was also a lack of sensibility, an almost animal callousness, on the coldly lit eyes and unflinching mouth, which readily suggested some terrible and recent experience--something potent enough to have dried up the human nature out of the man and left him soulless.
Eye colors depend on the amount of pigment (melanin) found in the iris and how it is distributed. Light gray-blue eyes contain much less pigment than extremely dark brown eyes. And there are many shades of eye color in between.
What color are hazel eyes? This color is semi-rare and is a combination of several other colors including green and brown. Hazel eyes have less melanin than brown eyes, but more than blue eyes. This eye color can be difficult to define since there is often substantial variation in this eye color. Hazel eyes often appear to shift in color from brown to green.
