WebbHue is the perceptual attribute associated with elementary color names. Hue enables us to identify basic colors, such as blue, green, yellow, red and purple. People with normal color vision report that hues follow a natural sequence based on their similarity to one another. With most color deficits, the ability to discriminate WebbColor perception is both physical and psychological. It involves the eye, but also the mind. Whether side-by-side or from afar, memory is a factor that affects our ability to see, describe, and match colors. There are a couple of different ways color is affected by memory. First, memory affects the way we name and perceive colors.
