$\huge\color{violet}{\mid{\fbox{\tt{AnswEr}}\mid}}$

Intensity (also called chroma or saturation) is the brightness or dullness of a color. A color as we see it on a color wheel is at full intensity (bright). When we mix it with gray, black, or white, it becomes dull. Colors also lose intensity when mixed with their complement (the opposite color on the wheel).

Answer 2

Answer:Intensity

Explanation:  Brightness refers to intensity, distinguished by the amount of shading mixed with the hue. Any desired hue of light can be produced when various amounts of two of the primary colors of light—the primary colors being red, green, and blue—are combined mechanically, either by addition or by subtraction.

Colorless - Dull or lacking in color. ... Monotone - All one color. Muted - Subdued or softened colors. Neutral - Having very little color. Pale - Something light in color or washed out.
