Call this code on your buttonclick event

C#

foreach (Control control in this.Controls)
           {
               if (control is Label)
               {
                   (control as Label).ForeColor = Color.Red;
               }
           }

Chris Ross' solution using modern .NET style looks better, but yours is also useful if OP uses .NET < 3.

Something like this should do the trick (assumes that the code is part of a method on the form):

XML

Color newColor = Color.Red;
foreach (var lbl in Controls.OfType<Label>())
    lbl.ForeColor = newColor;

cool code - If OP's Labels are not on one Form he could just "collect" them together to a "global" List of type Label(-References).
