Define base color, highlight, and lowlight concepts in hair color.

• A. Base color is the natural or primary hair color; highlights are lighter sections; lowlights are darker sections to create contrast.
• B. Base color are highlights; highlights are darker; lowlights are natural color.
• C. Base color is the darkest shade; highlights and lowlights refer to texture.
• D. Base color refers to root color only.

Answer: (A)

Understanding how base color, highlights, and lowlights relate helps explain how dimensional hair color is achieved. The base color is the foundation—the natural or primary shade that underlies the hair. Highlights are lighter strands added on top of that base to brighten and bring light into the look, while lowlights are darker strands inserted to deepen the color and add depth. The combination creates contrast and dimension rather than a flat, single shade.

That’s why the correct description fits: base color as the underlying foundation, highlights as lighter sections, and lowlights as darker sections to create contrast. The other options mix up the roles—highlights aren’t darker, lowlights aren’t simply the natural color, base color isn’t necessarily the darkest shade or about texture, and base color isn’t limited to roots only.
