<p class="MsoNormal">Generally, when plotting, curves’s color
are taken in the range color [1 3 5 7 9 11 13 15], where 1 is
the black color.<o:p></o:p></p>
<p class="MsoNormal">So, the first curve is black<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a general way to modify this
vector as to get another one with blue as first curve.</p>

<p>But then, in all forthcoming graphical figures, blue and black
colors of the default color map will be switched, for all kinds of
plots.<br>
Not sure that's a good idea.</p>
