+<ul>
+<li>
+With option COL <tt>TProfile2D</tt> histograms are handled differently because, for this type of 2D
+histograms, it is possible to know if an empty bin has been filled or not. So even
+if all the bins' contents are positive some empty bins might be painted. And vice versa,
+if some bins have a negative content some empty bins might be not painted.
