Thanks for your time on this smaller issue.  The patch works for me so I applied it in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/4cab008d3be1) and am closing this report.

The attached patch appears to solve the reported problem, but there are a number of other cases in the _quiver_ function and I'm not sure whether others also need to be changed.

Matlab uses black for the arrow color in quiver3 plots which has better contrast with the background than choosing a color from the current colormap.  See quiver_3_2_1.png at http://octave.sourceforge.net/compare_plots/
