Button BackColor doesn't change

I want to change my button's color when it has a default color. I tried with code that in below but it doesn't work. How can I do that?

public void ClickedButton (object sender, EventArgs e)
{
    if ((sender as Button).BackColor == System.Drawing.SystemColors.Control) {
        (sender as Button).BackColor = Color.Turquoise;
    }
}

Try casting the sender to a Button first:

public void ClickedButton (object sender, EventArgs e)
{
    var btn = sender as Button;
    if ((btn != null) && btn.BackColor == System.Drawing.SystemColors.Control)) {
        btn.BackColor = Color.Turquoise;
    }
}

If this is a Windows Form control, that should work.

If this is a Web Form control, it may not (unless you are calling it as part of a postback).

You need to add debug line to verify the current color of the button

public void ClickedButton (object sender, EventArgs e)
{
    // add debug line here 
    string message = (sender as Button).BackColor.ToString();
    Debug.WriteLine(message);

    if ((sender as Button).BackColor == System.Drawing.SystemColors.Control) {
        (sender as Button).BackColor = Color.Turquoise;
    }
}

That will help with your troubleshooting of code. Also there is nothing wrong with your current code. Below is the result.
