Decolorizing the hair's natural pigment allows the colorist to create the exact degree of which pigment?

• A. Primary pigment
• B. Contributing pigment
• C. Neutral pigment
• D. Secondary pigment

Answer: (B)

Decolorizing removes the hair’s natural pigment so you have a clean canvas to control tone. The final shade’s tonal character comes from the contributing pigment—the undertone the color deposit provides after lift. By lifting to the right level, you reveal the base that will accept this exact contributing pigment, and choosing the right toner or dye lets you dial in the precise degree of that pigment to achieve the target shade. The other terms don’t fit as well here because this concept centers on the undertone you shape through lifting and toning, not on base or neutral/noted pigment categories.
