The largest block on either exam — 39% of the clinical test, about 25 of its 65 questions. Levels and tones, the underlying pigment exposed at each stage of lift, neutralizing with the complement, developer volumes, the four categories of color product, and virgin application order. Almost everything here is reasoning, not recall: you are shown a starting level and a target and asked what actually gets you there.
Where people lose points
- Level is lightness or darkness. Tone is warmth or coolness. They are two independent axes and the exam separates them on purpose — a level 7 can be ash, neutral or gold, and changing tone is not the same job as changing level.
- Underlying pigment is exposed in a fixed order as you lift: red, red-orange, orange, yellow-orange, yellow, pale yellow. If you cannot recite that sequence you cannot answer a neutralizing question, because the tone you have to cancel is whatever stage you stopped at.
- Neutralize with the complement, not with more of the same family. Blue cancels orange, violet cancels yellow, green cancels red. Adding gold to brassy hair makes it brassier.
- Developer volume controls lift, not deposit: 10 volume deposits, 20 lifts one to two levels, 30 lifts two to three, 40 lifts three to four. More volume is not stronger color — it is more lift and more damage.
- Permanent color cannot lighten hair that has already been tinted. "Color does not lift color" — to go lighter on previously colored hair you need a lightener or a color remover, and the exam will offer you the tempting wrong answer of a higher-volume developer.
