  <p>PREREQUISITE: User agent needs to have an enabled and capable grammar error module. If it does not, then this test does not apply to such user agent.

  <ul>
    <li>if each glyph of the sentence is yellow
    <li>if "thing" has a desaturated lime green background
    <li>if the other words have a very lite blue background and
    <li>if there is no red.
  </ul>
