Which color scheme is characterized by a single color of low chroma?

The color scheme characterized by a single color of low chroma is best described as tonal. A tonal color scheme utilizes variations in the same hue, incorporating different tints (adding white) and shades (adding black) of that hue, while keeping the chroma or intensity low. This creates a harmonious and cohesive look throughout a space, often resulting in a serene and subtle aesthetic that can enhance the mood of an interior design.

Monochromatic schemes, while also based on a single hue, typically include both low and high chroma variations and may involve more vibrant tones. Analogous and complementary color schemes relate to color relationships on the color wheel; analogous schemes use colors that are next to each other, while complementary schemes are built on colors that are opposite each other. In contrast, the tonal scheme's focus on a singular hue with low chroma makes it distinct and fitting for environments seeking a gentle, uniform appearance.
