How do I tell hazel eyes from brown eyes?

Look at the iris under natural daylight. Hazel eyes lean toward brown-green with a slight warm / amber undertone, while brown eyes are deep brown with a slight warm / amber undertone. The free Eye Color Identifier removes the guesswork — it samples the actual pixels of your iris and assigns the closest color family.

Hazel eyes occur in about 5% of the world population. Brown eyes occur in about 79%. Hazel eyes are rarer.

Are hazel and brown eyes genetically related?
