a System.Drawing.Color
Use the Style.ForeColor property to specify the foreground color of the Web server control. The foreground color is usually the color of the text. This property will render on browsers earlier than Microsoft Internet Explorer version 4 for all controls, except the System.Web.UI.WebControls.Image, System.Web.UI.WebControls.AdRotator, System.Web.UI.WebControls.HyperLink and System.Web.UI.WebControls.LinkButton.
On browsers that do not support styles, this property is rendered as a FONT element.
