Final answer:
A color lighter than a hue's normal value is called a tint, which is achieved by adding white to the original color. Tints are generally lighter and often associated with a cheerful, pastel appearance.
Step-by-step explanation:
The term used to describe a color lighter than a hue's normal value is tint. A tint is created when white is added to a color, which increases its lightness. This is in contrast to a shade, which is what we get when black is added to a color, causing it to be darker than the original hue. The concept of value in art is critical because it allows artists to create depth and dimensions in their work by providing variations of lightness and darkness of colors. High-keyed values are near the lighter end of the spectrum and are usually cheerful, such as pastel colors, while low-keyed values are darker and may convey a moodier feeling.
