Yes, very dark eyes, often appearing black, are relatively rare. While true black eyes don't exist, extremely dark brown eyes that look black under certain lighting conditions are among the less common eye colors.
While brown is the most common eye color globally, the shade of brown significantly impacts rarity. Lighter shades of brown are more prevalent than darker shades. Because of this, the exceptionally dark brown shade that presents as black is considered rare. This perception of black comes from the high concentration of melanin in the iris.
Here's a breakdown to illustrate:
- Brown: Most common eye color worldwide.
- Light Brown/Hazel: More common than very dark brown.
- Very Dark Brown (Appearing Black): Relatively rare.
- Blue: Common in some populations, less so globally.
- Green: Uncommon.
- Gray: Uncommon.
- Amber/Violet: Very rare.
In conclusion, while brown eyes are common, very dark brown eyes that are easily mistaken for black are indeed a less frequently observed trait.
