2“To send light into the darkness of men's hearts - such is the duty of the artist.” Robert A Schumann
3ValueAn element of art, value refers to the lightness or darkness of a color. Value becomes critical in a work which has no colors other than black, white, and a gray scale. For a great example of value in action, think of a black and white photograph. You can easily visualize how the infinite variations of gray suggest planes and textures.
4Gray Scale or Value Scale Stepped grades of value gray scale - The range of neutral values, or shades of gray in an image. The gray scales of scanners and terminals are determined by the number of grays, or steps between black and white, that they can recognize and reproduce.
5Gradual Value Scalegradation - A gradual, smoothly nuanced, step-by-step change from dark to light values or from large to small shapes, or rough to smooth textures, or one color to another. As a principle of design, it refers to any way of combining elements of art by using a series of gradual changes in those elements. Gradation is unlike contrast which stresses sudden changes in elements.

8Value in ColorEach color out of the tube are at different values. Notice the dots in the columns. They indicate which cell matches the others in value. When you add black to a color it is a shade of that color. When you add white it is a tint of that color. More on that later...
9ChiaroscuroA word borrowed from Italian ("light and shade" or "dark") referring to the modeling of volume by depicting light and shade by contrasting them boldly.
