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. cannon marlin downrigger owners manualWebbSaturation defines the brilliance and intensity of a color. When a pigment hue is “toned,” both white and black (grey) are added to the color to reduce the color’s saturation. In terms of the “additive” light color model, though, saturation works on a scale based on how much or how little other hues are represented in the color. fizi bathroom
