Lamp控件指定不闪烁时的颜色（比初始颜色少），提示数组越界异常

Lamp控件指定不闪烁时的颜色？查了源码并没有发现可以指定最终显示颜色方法（不闪烁）
初始设置2种颜色（RED,LIME）源码中使用了intColorIndex在onPaint用于实现每次闪烁时重绘颜色。当重新指定LampColor=new Color[]{ Color.RED } 为一种颜色时，因为intColorIndex可能会大于1，此时onPaint重绘方法获取的LampColor[intColorIndex]会提示数组越界。

```
protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);
            var g = e.Graphics;
            g.SetGDIHigh();

Color c1 = lampColor[intColorIndex];//这一行会数组越界
            GraphicsPath path = new GraphicsPath();
            path.AddLine(new Point(m_rectWorking.Left, m_rectWorking.Bottom), new Point(m_rectWorking.Left, m_rectWorking.Top + m_rectWorking.Width));
            path.AddArc(new Rectangle(m_rectWorking.Left, m_rectWorking.Top, m_rectWorking.Width, m_rectWorking.Width), 180f, 180f);
            path.AddLine(new Point(m_rectWorking.Right, m_rectWorking.Top + m_rectWorking.Width), new Point(m_rectWorking.Right, m_rectWorking.Bottom));
            path.CloseAllFigures();
            g.FillPath(new SolidBrush(c1), path);

g.FillRectangle(new SolidBrush(lampstand), new Rectangle(5, m_rectWorking.Bottom - 19, this.Width - 10, 10));
            g.FillRectangle(new SolidBrush(lampstand), new Rectangle(0, m_rectWorking.Bottom - 10, this.Width, 10));
        }
```
期待提供指定颜色（非闪烁时）的方法。
