Returns or sets a Single that lightens or darkens a color.
expression A variable that represents a Border object.
You can enter a number from -1 (darkest) to 1 (lightest) for the TintAndShade property. Zero (0) is neutral.
Attempting to set this property to a value less than -1 or more than 1 results in this run-time error: "The specified value is out of range." This property works for both theme colors and nontheme colors.
Note that the visual properties of a Border object are interlocked; that is, changing one property can induce changes in another. In most cases, the induced changes serve to make the border visible (which may or may not be desirable). However, other (more unexpected) results are possible. For an example, see the Border object.
