It sounds like you’re asking about a T1b/4 hair wig — here’s a quick overview:

T1b/4 is a hair color blend commonly used in wigs and hair extensions.

T1b usually refers to a very natural black or off-black shade.

4 is typically a medium brown color.

Together, T1b/4 means the roots are a darker blackish tone (T1b) that gradually blends into a medium brown (4). This creates a natural-looking ombré or balayage effect.
