Please help me how to change toolStripComboBox highlighted colour instead of Blue colour in windows form using c#

What I have tried:

private void toolStripComboBox1_Paint(object sender, PaintEventArgs e)
{
    foreach (ToolStripComboBox item in toolStrip1.Items)
    {
        var asComboBox = item;
        if (asComboBox != null)
        {
            var location = asComboBox.ComboBox.Location;
            var size = asComboBox.ComboBox.Size;
            Pen cbBorderPen = new Pen(Color.Gray);
            Rectangle rect = new Rectangle(
                                   location.X - 1,
                                   location.Y - 1,
                                   size.Width + 1,
                                   size.Height + 1);

            e.Graphics.DrawRectangle(cbBorderPen, rect);
        }
    }
}
