Remarks
A predefined color is also called a known color and is represented by an element of the KnownColor enumeration. When the ToKnownColor method is applied to a Color structure that is created by using the FromArgb method, ToKnownColor returns 0, even if the ARGB value matches the ARGB value of a predefined color. ToKnownColor also returns 0 when it is applied to a Color structure that is created by using the FromName method with a string name that is not valid.
