I have an array that I declare above my form load:

protected string[] Colors = new string [3] {\"red\", \"green\", \"orange\"};

You have to store the number of clicks in your ViewState and increase it by one in your button's click event handler.

private int NumberOfClicks
{
   get { return (int)(ViewState["NumberOfClicks"] ?? 0 );
   set { ViewState["NumberOfClicks"] = value; }
}


protected void btn_Click(object sender, EventArgs e)
{
   if(NumberOfClicks < colorArray.Length)
   {
           //write to response colorArray[NumberOfClicks];
           NumberOfClicks += 1;
   }
}
