RTF in a RichTextBox

Note that even if you pre-load a color table, the RichTextBox controll will DELETE color entries which aren't immediately used. This isn't good for creating a color table then using the colors later. I end-up using the webbrowser controller rather than the richtextbox controller for displaying formatted text.

// prepare the RichTextBox with a header (and colors) to accept RTF text
rtbConsole.Clear();
rtbConsole.Rtf = @"{\rtf1\ansi\deff0{\colortbl ;\red255\green255\blue0;\red0\green150\blue0;}}";
string message = "this is a {\b bold} example";

// appending text
rtbConsole.SelectedRtf = "{\\rtf1\\ansi "+ message.Replace("\n", "\\line") + "}";
