Final answer:
The term for colors with no saturation and no hue, such as white, black, and gray, is 'neutral colors'. These colors differ from primary, secondary, and tertiary colors, which have varying degrees of saturation and can be shown on a color wheel.
Step-by-step explanation:
The term used to describe colors that have no saturation and therefore no hue, such as white, black, or gray, is neutral colors. Since neutral colors do not have saturation, they do not display colorfulness or hue. In contrast to primary, secondary, and tertiary colors, which are based on varying degrees of saturation and can be positioned on a color wheel, neutral colors such as whites, blacks, and grays function differently as they affect the value (lightness or darkness) of a color when added. White and black are often used to create tints (lighter) and shades (darker) of a color respectively but do not add hue themselves.
