Which of the following describes the addition of black to a hue?

The addition of black to a hue is referred to as shades. When black is mixed with a color, it darkens that color, resulting in a deeper tone known as a shade. This process affects the overall visual properties of the color, creating a richer and often more dramatic version of the original hue.

In contrast, tints are created by adding white to a hue, which results in a lighter version of that color. Neutral colors refer to colors that do not appear on the color wheel, such as beige, gray, and white, and do not specifically pertain to the concept of darkening a hue. Accent colors are those used to complement or highlight a primary color but do not describe the alteration of a hue through the addition of black. Therefore, the correct term for the process of incorporating black into a hue to create a darker variation is shades.
