Use the ForeColor attribute:

 RequiredFieldValidator1.ForeColor = System.Drawing.Color.Red;

You just changed your question from CustomValidator to RequiredFieldValidator. And yes I use this code and it works.

No problem. By the way, I recommend you use SetFocusOnError="true" and Display="Dynamic" for more user-friendly result.

Something like this should work:

Style myStyle = new Style();
s.BackColor = System.Drawing.Color.Red;

valEmailRecipients.Style = myStyle;

Or simply:

valEmailRecipients.Style.ForeColor= System.Drawing.Color.Red;

See here for reference and here as well.

I am getting error - 'System.Web.UI.CssStyleCollection' does not contain a definition for 'ForeColor'. Also .. Property or indexer 'System.Web.UI.WebControls.WebControl.Style' cannot be assigned to -- it is read only

@Lijo yes, because you changed the Type of control. You had originally posted a very different markup which had a CustomValidator not a RequiredFieldValidator.
