Color #4 is a very dark brown.
Texture is a light yaki which makes this unit tangle less and easier to brush through.
Higher density near the head, low density as it gets longer. Makes it look more natural.
It's VERY long. Hits just above my butt, I'm 5'8" and have a long torso.
Lace is transparent, knots are minimal.
Lots of baby hairs!
I really like this unit and may repurchase in a different color.
