Hello junkone,

I believe the simple solution for this would be to use a brush, or the following:

NinjaTrader.NinjaScript.Alert.AlertCallback(e.Execution.Instrument, this, DateTime.Now.ToString(), NinjaTrader.Core.Globals.Now, Priority.High, e.ToString(), [email]NinjaTrader.Core.Globals.InstallDir+@"\sounds\Alert1.wav[/email]",[B] Brushes.Blue, Brushes.White[/B], 0);

If you are creating a totally new brush, I would suggest to review the items on this page about working with Brushes: http://ninjatrader.com/support/helpG...lightsub=brush

Using the Standard colors like White or Blue you should be able to use the pre-defined system brushes, if you are creating a new brush you could use the SolidColorBrush example in the help guide.

Please let me know if I may be of further assistance.
