The underline color.
The color can be specified using a system-defined color (for example,
Color.Yellow),
can be translated from an HTML color code using the method
Color.FromHtml,
or created from RGBA values using the method
Color.FromRgba.
The RGBA red, green, blue, and alpha components must have values between 0.0f (0%, 0 byte value) and 1.0f
(100%, 255 byte value). The alpha component is optional, its value is 1.0f by default, which means that the color
is fully opaque. |
