///   Never convert native constants (such as <see cref="PInvoke.CLR_NONE"/> to <see cref="Color"/> or pass them through
///   any conversion in <see cref="Color"/>, <see cref="ColorTranslator"/>, etc. as they can change the value.
///   <see cref="COLORREF"/> is a DWORD- passing constants in native code would just pass the value as is.
