Gets or sets the shade that is applied to the theme color in the HoverColor property of the specified object. Read/write Single.
The HoverShade property contains a numeric expression that can be used to darken the theme color in the HoverColor property. The default value of the HoverShade property is 100, which is neutral, and does not change the theme color. To darken the color, first determine the percentage by which to darken from 1 to 100, then subtract that value as a whole number from 100 and store the remainder.
