AmbientProperties Class
Assembly: System.Windows.Forms (in system.windows.forms.dll)
An ambient property is a property on a control that, if not set, is retrieved from the parent control. If the control does not have a parent and the property is not set, the control tries to find the value of the ambient property through the Site property. If the control is not sited, the site does not support ambient properties, or the property is not set on the AmbientProperties object, the Control uses its own default values. Some objects derived from the Control class might set the property even if you do not. For example, the Form class always sets the ForeColor and BackColor properties.
