I want to create an alert effect on a button by cycling between two colors randomly.

What I have tried:

private void timer1_Tick(object sender, EventArgs e)
       {
           Random rand = new Random();
           int A = rand.Next(256);
           int R = rand.Next(256);
           int G = rand.Next(256);
           int B = rand.Next(256);
           NotificationBtn.BackColor = Color.FromArgb(A, R, G, B);
       }

But this cycles between a lot of colors i need only two colors.

Why not create 2 random colors, store them in an array with 2 elements, and flip between the 2? or make color variables set each one to a random color and them flip between those 2 variables?

int timeleft = 2;
        private void timer1_Tick(object sender, EventArgs e)
        {
            Color color1 = Color.Red; 
            Color color2 = Color.WhiteSmoke; 

            if (timeleft > 0)
            {
                NotificationBtn.BackColor = color1;
                timeleft = timeleft - 1;
            }
            else
            if(timeleft == 0)
            {
                NotificationBtn.BackColor = color2;
                timeleft = timeleft + 2;
            }
        }
