When researching, I came across this,
Wolf pups have blue eyes when they're born, but the color changes as they mature- for a while, all wolves have green eyes! However, adults' eyes are yellow, amber, orangish, or brown. ... (Can't stress this enough - adult wolves NEVER have blue eyes). Gray or green eyes in an adult wolf is known, but very rare.

Is this true?
