The test fails if you see any red, the text "FAIL" below the two rectangles below or if any of the expected results below don't happen.
<ol>
<li>You should see a green and a yellow rectangle, stacked vertically.</li>
<li>Move the mouse over the green rectangle. <strong>Expected: </strong>The color should change to a lighter green.</li>
<li>Click in the green rectangle. <strong>Expected: </strong>The color should change again to a yet lighter green.</li>
<li>Move the mouse over the yellow rectangle.</li>
<li><strong>Expected: </strong>The color of the green rectangle should change yet again to a pale green. There should be a green text below that says "PASS".</li>
