Kim Taehyung, also known as V of the popular K-Pop group BTS, does not have naturally green eyes. While he has been seen with green eyes in some photos and videos, this is most likely due to the use of colored contact lenses.
It's important to remember that Korean people, including all the BTS members, generally have dark brown eyes. The use of colored contacts is quite common in the K-Pop industry, and many idols use them to create different looks for their performances and photoshoots.
Therefore, while Kim Taehyung may wear green contacts, his natural eye color is brown.
