Here's one for people more familiar with the .NET framework and languages that rely on it, specifically in this case C#.

This is an extension of the 'RichTextBox' class that redefines 'AppendText' to include a colour option. Somewhat simple but very useful.

Code:

   // Define a class 'RichTextBoxExtensions'. Make sure to put this in yuor namespace and not in another class.
   public static class RichTextBoxExtensions
   {
       // define the AppedText void. This accepts 'this' (RichTextBox object) which will be referred to as '
                                                // text (string type) which is the contents to append to the RichTextBox.
                                                // and colour (Color object) used to define the texts colour.
       
       public static void AppendText(this RichTextBox box, string text, Color colour)
       {
            // Most of this is standard from the default RTB, assuming you're reading into this I'll imagine you know what that does...
           box.SelectionStart = box.TextLength;
           box.SelectionLength = 0;

           box.SelectionColor = colour; // Change the colour, simples.
           box.AppendText(text);
           box.SelectionColor = box.ForeColor;
           box.ScrollToCaret(); // Also, scroll to caret (scroll to the bottom of the RichtextBox). Nice for keeping new appended text always on top ;)
       }
   }
