Value indicates the lightness of a color. The scale of value ranges from 0 for pure black to 10 for pure white. Black, white and the grays (as shown in figure 2) between them are called “neutral colors”. They have no hue. Colors that have a hue are called “chromatic colors.”
The value scale applies to chromatic as well as neutral colors. The value scale is illustrated for all neutral colors on the chart labeled Munsell’s Nearly Neutral, included in this book of color.
