What term describes a specific hair color that indicates a visible difference between colors?

The term that describes a specific hair color indicating a visible difference between colors is "shade." In the context of hair color, shade refers to the variation of a hue and encompasses the specific character of a color, often reflecting lightness or darkness. For instance, within the broader hue of blonde, you could have shades like platinum blonde, golden blonde, or ash blonde. Each of these shades offers a distinct visual difference, allowing clients to choose precisely how they want their hair to appear.

Hue, while related, refers more broadly to the name of the color itself (like red, blue, or yellow) without emphasizing the lightness or darkness. Tone refers to the warmth or coolness of a color but does not denote a specific color difference in itself. Color depth usually pertains to the intensity or richness of a color and is not specifically about visibly differentiating between two hues or shades. Thus, the correct choice emphasizes the specific nature of the visible differences in colored hair that clients often seek.
