1. Also called lightness/darkness or luminance. This refers to the perception of a color as to its proximity to black or white. Burgundy, Red and Pink have the same hue and saturation, but differ in Brightness (although, in some schools of thought white and black are “neutral”—being values of gray—and thus these three colors would vary in saturation as well as brightness). 2. In printing, the brightness of a sheet of paper measures the percentage of blue light it reflects. The brightness of a piece of paper is typically expressed on a scale of 1 to 100 with 100 being the brightest. Most papers reflect 60-90% of light. The brightness of a paper affects readability, the perception of ink color and the contrast between light and dark colors. “Bright white” refers to papers that are in the high brightness range (85% to 95%) and are visually “bluer” than regular white papers, which may have a yellow cast. The current trend in paper making is to make them as bright as possible.a
