How to change the label disabled forecolor

[TBBW]

As the title suggests,
how to change the standard (default) forecolor when the label is disabled.

I came up with the following:

namespace COD
{
    class CustomLabel : System.Windows.Forms.Label
    {
        private bool _enabled = true;

        protected override bool Enabled
        {
            get
            {
                return _enabled;
            }
        
            set
            {
                _enabled = value;

                if (_enabled)
                    this.ForeColor = Color.FromKnownColor(KnownColor.Yellow);
                else
                    this.ForeColor = Color.FromKnownColor(KnownColor.Red);
            }
        }
    }
}

but it is not working ....
