想用系统的这个选择工具，加上代码 DispId(unchecked((int)0xFFFFFDFF))即可

在源码中，ForeColor   -》  DispId(NativeMethods.ActiveX.DISPID_FORECOLOR)，但由于NativeMethods.ActiveX.DISPID_FORECOLOR访问级别不够，直接找到定义的int来替代

BackColor-》 DispId(NativeMethods.ActiveX.DISPID_BACKCOLOR)

public const int DISPID_BACKCOLOR = unchecked((int)0xFFFFFE0B);
