Why Can I only see Red Color when drawing three points which have three colors?

This is my All code.

Device device = null;
VertexBuffer vertexBuffer = null;
public bool Initialize()
{
PresentParameters presentParams = new PresentParameters();
presentParams.Windowed=true;
presentParams.SwapEffect = SwapEffect.Discard;
device = new Device(0, DeviceType.Hardware, this, CreateFlags.SoftwareVertexProcessing, presentParams);
this.OnCreateDevice(device, null);
return true;
}
public void OnCreateDevice(object sender, EventArgs e)
{
Device dev = (Device)sender;
vertexBuffer = new VertexBuffer(typeof(CustomVertex.TransformedColored), 3, dev, 0, CustomVertex.TransformedColored.Format, Pool.Default);
vertexBuffer.Created += new System.EventHandler(this.OnCreateVertexBuffer);
this.OnCreateVertexBuffer(vertexBuffer, null);
}

public void OnCreateVertexBuffer(object sender, EventArgs e)
{
Console.WriteLine("Call!!");
VertexBuffer vb = (VertexBuffer)sender;
GraphicsStream stm = vb.Lock(0, 0, 0);
CustomVertex.TransformedColored[] verts = new CustomVertex.TransformedColored[3];
verts[0].X=150;verts[0].Y=50;verts[0].Z=0.5f; verts[0].Color = System.Drawing.Color.Red.ToArgb();
verts[1].X=150;verts[1].Y=150;verts[1].Z=0.5f; verts[1].Color = System.Drawing.Color.Yellow.ToArgb();
verts[2].X=50;verts[2].Y=50;verts[2].Z=0.5f; verts[2].Color = System.Drawing.Color.Green.ToArgb();
stm.Write(verts);
vb.Unlock();
}
private void Render()
{
if (device == null) {return;}
device.Clear(ClearFlags.Target, System.Drawing.Color.Blue, 1.0f, 0);
device.BeginScene();
device.SetStreamSource( 0, vertexBuffer, 0);
device.VertexFormat = CustomVertex.TransformedColored.Format;
device.SetRenderState(RenderStates.ShadeMode,2);

device.DrawPrimitives(PrimitiveType.TriangleList, 0, 1);
device.EndScene();
device.Present();
}
protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
{this.Render(); }

And How to set FVF?Can You tell me?

How do I upload the image?

I try to use insert link.But it is disabled.

If Light is ON : (and one light is defined...not a spot light but a global Light)

ColorVertex=MaterialColor * (AmbientColor + Light1 +Ligth2...)

And You need to specify the ColorOp, ARG1 and ARG2

In your case you would need ColorOp to be SELECTARG1 and ARG1 to be Diffuse (ARG2 is not used)

Did you put the LIGHT on or off ?
If you have Light ON you need to define one Light...or an ambient value (a state value)

With Light OFF the Color come only from the Vertex Color Value (not the formula above)
