For Window Form application :

C#

private void button3_Click(object sender, EventArgs e)
        {
            button3.BackColor = System.Drawing.Color.Black;
        }

For Web Page :

On Page level declare static variable:

C#

static bool Isdefault= true;
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                Isdefault = false;
            }
        }

and in button click event write :

C#

protected void Button1_Click(object sender, EventArgs e)
       {
           if (!Isdefault)
           {
               Button1.BackColor = System.Drawing.Color.GreenYellow;
           }
       }

Just check out the following, maybe it will help you:

C#

public void single_button_Click(object sender, EventArgs e)
  {
    Button btn = (Button)sender;
    if (btn.BackColor == Color.Red)
    {
      btn.BackColor = SystemColors.Control;
    }
    else if (btn.BackColor == SystemColors.Control)
    {
      btn.BackColor = Color.Red;
    }
  }

I used in the asp.net c# web page. It is not working. It gives an error stating that:

The name 'color' and 'SystemColors' does not exist in the current context

You didn't specify so I thought maybe its for winform. Include System.Drawing.Color namespace at the top and you will get some colors.

I uncluded 'using System.Drawing.Color' at the top. It says :"using namespace directive can only be applied to namespaces; 'System.Drawing.Color' is a type not a namespace"

ok then maybe try using color like this:
string hexValue = "#000000"; // You do need the hash
Color colour = System.Drawing.ColorTranslator.FromHtml(hexValue); // Yippee

If its a windows based application then,

change the property of your button's flat style to "Standard" ane on click write the below:
button1.BackColor = Color.Red;

it will work fine.

What exactly you mean it did not work,

If this is windows application written in C#,

C#

button1.BackColor = Color.Green;

Just check, which event you are wiring up. Post some more code for us to see.
