Which statement accurately defines level and undertone in hair color?

• A. The level describes lightness/darkness; undertone refers to the dominant hue present (cool, warm, neutral).
• B. The level indicates the hair's moisture content and porosity.
• C. Undertone describes moisture content.
• D. Level describes the hair's curl pattern.

Answer: (B)

Level describes how light or dark the hair is on a scale from dark to light, while undertone refers to the dominant hue within that shade (cool, warm, or neutral). This pairing explains how a color will actually appear after processing and helps you predict the final result. The statement that level is about lightness/darkness and undertone is the accurate definition. Moisture content and porosity relate to how hair absorbs or holds moisture and color and to texture, not to the definitions of level or undertone. Curl pattern is about texture, not color.
