Explain the difference between hair color level and tone and how they determine the final shade.

• A. Level is the hue family; tone is lightness/darkness
• B. Level indicates lightness or darkness; tone indicates the hue family; the combination yields the final shade
• C. Level is the chemical strength; tone is conditioning level
• D. Level is the scalp sensitivity; tone affects porosity

Answer: (B)

Level shows how light or dark the hair will be after processing, essentially the lightness or darkness you’re aiming for. Tone describes the hue or warmth within that level—think ash, beige, gold, copper, or red. The final shade comes from combining both: the level sets the darkness, and the tone defines the color family within that darkness. So a lighter level with a cool tone gives a cool light shade, while the same level with a warm tone gives a warm light shade; a darker level will yield a deeper version of the same tone. For example, level 8 with an ash tone yields a light, cool blond with ash undertones; level 8 with a gold tone yields a light, warm blond with golden warmth. This pairing is what determines the exact final shade.
