Answer:
C. Contrast
Explanation:
In the RGB color scheme, hue, brightness, contrast and saturation are all aspects of the color (of an image).
Hue of a color is the property of that color when no shades have been added to it.
Saturation describes how vivid an image (color) is.
Brightness is how light or dark an object (image) is.
Contrast is the effect that combines both the brightness of a color (or image) and the difference in the colors that make up that image. Contrast will affect the luminescence of an object. By luminescence, we mean, the degree of light falling on an object.
