How is the Value Scale section used?
The Value Scale section is used to compare with underlying colors, to judge their lightness or darkness. Also, of course, these contain the codes for the web-safe gray scale values. Although it would be nice to have a gray scale that could be placed over every color on the wheel, this was not physically possible. For a more useful gray scale, the Color Wheel Company does offer a Gray Scale and Value Finder for use with all colors.
