Final answer:
A color that is almost gray has low saturation because the intensity of the original color has been significantly diminished through the addition of white or black.
Step-by-step explanation:
A color that is almost gray has low saturation. Saturation refers to the intensity of a color. A fully saturated hue is vibrant and at its most pure form. As saturation diminishes, colors become more washed out or diluted, and more similar to gray.
Therefore, when a color is described as almost gray, it means that it has been significantly desaturated, often because of the addition of white or black to the original color, resulting in it having a low level of saturation.
