Follow-up Comment #2, bug #55002 (project octave):

It would still be useful to see what Matlab does, but I guess when there are
multiple colored object in the first axes there is no reasonable way to
determine which one is more important and should be the one that colors the
axes object.

THere is this bit of code in plotyy.m that addresses this subject.


  h1 = feval (fun1, x1, y1);

  set (ax(1), "xlim", xlim);
  if (isscalar (h1))
    ## Coloring y-axis only makes sense if plot contains exactly one line
    set (ax(1), "ycolor", getcolor (h1));
  endif
