If it's something simple like just searching for a character and modifying the color from it, you can do something like:

int inicio = richTextBox2.Text.IndexOf('|');
if(inicio >= 0)
{
    richTextBox2.SelectionStart = inicio;
    richTextBox2.SelectionLength = richTextBox2.Text.Length - inicio;
    richTextBox2.SelectionColor = Color.Red;
}
