Question

What base toner would be used to produce a neutral blond on prelightened pale yellow hair?

A) Blue-violet base
B) Red-orange base
C) Green-yellow base
D) Brown-black base

Answer 1

To neutralize pale yellow hair and achieve a neutral blond, a blue-violet base toner should be used as it is the complementary color that will counteract the yellow tones.

Step-by-step explanation:

To achieve a neutral blond color on prelightened hair that has a pale yellow undertone, the appropriate toner to use would be a blue-violet base toner. This is because a blue-violet base will counteract the yellow tones in the hair. According to color theory, blue and violet are opposite yellow on the color wheel, making them complementary colors. In hair coloring, using a toner with the complementary color can neutralize unwanted hues. This is similar to the process of coupling seen in Figure 21.6.11, where various couplers are used to achieve specific color results in the oxidation of p-phenylenediamine to quinonediimine in permanent hair coloring.
