public class Form1 : Form
{
    private TabControl tabControl1;
    private TabPage tabPage1;
    private TabPage tabPage2;

    private void MyTabs()
    {
        this.tabControl1 = new TabControl();
        this.tabPage1 = new TabPage();
        this.tabPage2 = new TabPage();

        this.tabControl1.Controls.AddRange(new Control[] {
            this.tabPage1,
            this.tabPage2});
        this.tabControl1.Padding = new Point(15, 10);
        this.tabControl1.Location = new Point(35, 25);
        this.tabControl1.Size = new Size(220, 220);

        // Highlights TabPage.Text when the mouse passes over tabs.
        this.tabControl1.HotTrack = true;
    
        this.tabPage1.Text = "myTabPage1";
        this.tabPage2.Text = "myTabPage2";

        this.Size = new Size(300, 300);
        this.Controls.AddRange(new Control[] {
            this.tabControl1});
    }
    
    public Form1()
    {
        MyTabs();
    }

    static void Main() 
    {
        Application.Run(new Form1());
    }
}

Remarks

The color that the tab changes to when the mouse is over it is determined by the local computer's system colors. To change the system colors, use Control Panel.
