_____ means a harmony based on one hue. This single hue may be varied in value and/or intensity.

Question

Accepted Answer

The correct option is 2:
The term you are looking for is Monochromatic harmony. As students of design theory, you must remember that 'mono' means 'one,' and 'chroma' means 'color.' Therefore, a monochromatic color scheme is based exclusively on a single base color, or **hue**, from the color wheel. This single color is then varied by altering its other two properties: **value** and **intensity**. The value is manipulated by adding white to create lighter versions called *tints*, or by adding black to create darker versions called *shades*. The intensity, or saturation, can be changed by adding gray to create *tones*. This combination of tints, shades, and tones of the same hue creates a quiet, restful, and highly unified visual effect. Designers frequently use this scheme to achieve sophistication and serenity in a space because the colors blend effortlessly, ensuring a harmonious composition that provides a sense of visual continuity and depth without being jarring.

The incorrect option is 1:
Achromatic harmony is an incorrect choice because the word 'achromatic' literally means 'without color' or 'colorless.' This scheme relies solely on neutral colors: black, white, and all the resulting shades of gray. While it does exhibit variations in value, it fundamentally lacks a *hue*, which is the base color property described by the first part of the question. Therefore, an achromatic scheme is a harmony based on neutrals, not on the variation of a single hue.

The incorrect option is 3:
Analogous harmony is incorrect because it involves using **multiple** hues, specifically two or more colors that sit adjacent to one another on the color wheel. For example, a common analogous scheme might include yellow, yellow-green, and green. Although analogous colors are considered harmonious because they share a common parent color and naturally blend well, they violate the core condition of the question, which requires the harmony to be based on *one* hue.

The incorrect option is 4:
Double complementary is a highly complex and contrasting color scheme, making it an incorrect answer. It involves using **four** colors, arranged as two distinct pairs of complementary colors. These four hues form a rectangle or square on the color wheel. While this scheme offers tremendous richness and vibrancy, it is far removed from the concept of being "based on one hue," which describes the simplest, most unified type of color harmony.
