Here's why you might be confused:
* Hair Type: You might be thinking of hair texture. The "5b" classification is used in the Andre Walker hair typing system to describe tightly coiled, very tightly packed curls. It's not related to hair color.
* Color Chart: In hair color charts, numbers often refer to shades of color, but "5b" is not a standard designation.
To understand hair color, you would typically need more information, like:
* Brand: Different hair color brands use different numbering systems.
* Color Level: Hair colors are often categorized by levels, with 1 being the darkest black and 10 being the lightest blonde.
* Color Tone: Hair color also has underlying tones like ash, warm, or cool.
Let me know if you have more information about the context of "5b" and I can help you find the corresponding hair color.
