{
     label1.Text = hScrollBar1.Value.ToString();
     this.Blue = hScrollBar1.Value;
}

private void hScrollBar2_Scroll(object sender, ScrollEventArgs e)
{
     label2.Text = hScrollBar2.Value.ToString();
     this.Green = hScrollBar2.Value;
}

private void hScrollBar3_Scroll(object sender, ScrollEventArgs e)
{
     label3.Text = hScrollBar3.Value.ToString();
     this.Red = hScrollBar3.Value;
}

private void hScrollBar4_Scroll(object sender, ScrollEventArgs e)
{
     label4.Text = hScrollBar4.Value.ToString();
     this.Tolerence = hScrollBar4.Value;
}

private void button1_Click(object sender, EventArgs e)
  {
      this.Blue  = hScrollBar1.Value;
      this.Green = hScrollBar2.Value;
      this.Red = hScrollBar3.Value;
      this.Tolerence = hScrollBar4.Value;
