Hi.Try This Method.If you are working with WPF.

<richtextbox x:name="MainRichTextBox" selectionchanged="MainRichTextBox_SelectionChanged" xmlns:x="#unknown">

and your code behind:

private void MainRichTextBox_SelectionChanged(object sender, RoutedEventArgs e)
{
RichTextBox richTextBox = e.OriginalSource as RichTextBox;
richTextBox.SelectionBrush = Brushes.Yellow;

//for access to your RichTextBox content
TextRange textRange = new TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd);
if (textRange.Text.Contains("TextBox"))
{
//Put your policy code here for changing Foreground color
}
}
I hope this help you.
Good Luck
