T1B/27 → This is a hair color code.

1B means natural soft black roots.

27 means honey blonde ends.

The “T” means “two-tone” or “ombre” — so it’s black at the top, blending into blonde.

Straight bob → The hair texture is straight, cut into a bob style (short, typically jaw- to shoulder-length)

So, T1B/27 straight bob would be a straight bob hairstyle with natural black roots fading into honey blonde tips.
