Try it.

If RichTextBox1.Text.Contains("<red>") Then
            RichTextBox1.SelectionStart = CInt(RichTextBox1.Find("<red>").ToString)
            RichTextBox1.SelectionLength = CInt(RichTextBox1.Find("</red>").ToString)
            RichTextBox1.Select(RichTextBox1.Find("<red>") + "<red>".Length, RichTextBox1.Find("</red>") - (RichTextBox1.Find("<red>") + "<red>".Length))
            RichTextBox1.SelectionColor = Color.Red
            MessageBox.Show("Format DETECTED!")
End If
