Which of the following defines a color's strength against white?

Saturation refers to the intensity or purity of a color, indicating how vibrant it appears in relation to white. A highly saturated color appears very vivid and rich, while a color with low saturation may look more washed out or grayed out. This concept is crucial in advertising design, where strong colors can attract attention and convey emotions effectively.

Understanding saturation allows designers to manipulate color effectively in their work, making it an important element in creating visually compelling advertisements. In contrast, tone, brightness, and hue relate to different attributes of colors. Tone pertains to the depth of color when mixed with gray, brightness relates to how light or dark a color is, and hue describes the color itself, such as red, blue, or green. Each of these elements plays a role in color theory but captures different characteristics than saturation.
