I think black hair really suits Wonpil haha.

Since DAY6's debut, Wonpil has tried out various hairstyles, including blonde, red, brown, and pink hair. We've been able to see him in many different hair colors and styles. However, over the past few years, it seems he has mostly stuck to black hair! Personally, I think black hair brings out Wonpil's visuals the best, so I like him the way he looks now.
