California Cosmetology Written ExamHaircoloringMedium
A colorist is formulating a target level 7 golden blonde result. The client's level 6 natural hair has an underlying pigment that reads slightly ash (cool). Which type of base should the colorist select in the formula to achieve the desired warm, golden final result?
- AA violet base, to neutralize yellow tones
- BA clear, no-lift base with no added pigment
- CAn ash base, to neutralize excess warmth
- DA gold or warm base, to add the warmth missing from the natural underlying pigment
Show answer & explanationAnswer & explanation
Correct answer: D. A gold or warm base, to add the warmth missing from the natural underlying pigment
Since the natural hair reads cooler/ash than the desired warm gold target, the colorist must add a gold/warm base to compensate for the missing warmth and achieve the intended golden result.
Why the other options are wrong
- A. Violet neutralizes yellow/brassy tones, which is unnecessary and counterproductive here.
- B. A clear base adds no pigment and would not correct the cool undertone.
- C. An ash base would push the result cooler, away from the desired gold outcome.
Base Color Formulation
Selecting a color base (warm, cool, or neutral) to compensate for or complement the natural underlying pigment and achieve the desired tonal result.
- Compare desired tone to natural underlying pigment before formulating
- Add missing warmth with gold/warm bases
- Add missing coolness with ash/violet/blue bases
Memory trick: Fill in what's missing—cool hair needs a warm boost to go gold.
