        }

        private void trackBar3_Scroll(object sender, EventArgs e)
        {
            textBox3.Text = trackBar3.Value.ToString();
            Form1 frm = this;
            frm.BackColor = Color.FromArgb(trackBar1.Value, trackBar2.Value, trackBar3.Value);
        }
    }
}

通过 FromArgb  0-255 的数值来设置颜色 ,加入了 TrackBar, 我想到了 win 8安装时 那个颜色渐变,就是采用这个原理,可以马上做一个.

接下来会做一个
