Final answer:
The term for a color with high lightness and strong saturation is 'Chroma'. It combines value (lightness) and saturation (intensity and purity) to give a color its vividness. High chroma colors appear vibrant, whereas lower saturation can lead to more muted hues.
Step-by-step explanation:
The term used to designate a color that has high lightness and strong saturation is Chroma. Lightness is often referred to as value, which indicates the degree of lightness or darkness of a color. Saturation refers to the intensity and purity of a color, where the primary colors are at their purest when fully saturated. Together, high lightness and strong saturation contribute to a color's chroma, making it appear vivid and intense. As saturation decreases, the color may start to look washed out, particularly when white or black is added, thus affecting its chroma.
An example of an artist using highly saturated colors is Henri Matisse in works like 'Red Room (Harmony in Red)', whereas Zhou Chen in 'Peach Blossom Spring' used less saturated colors for a more muted palette. In the context of value, adding white to a hue creates a tint with a higher value, while adding black to a hue creates a shade with a lower value.
