I fixed this on the development branch in this changeset: http://hg.savannah.gnu.org/hgweb/octave/rev/a150f1945ad0.

Marking as fixed and closing report.

As reported in https://octave.discourse.group/t/the-color-of-my-triangle-doesnt-change/1556

According to the "help fill"

 If C is a vector or matrix then the color data is first
     scaled using 'caxis' and then indexed into the current colormap.  A
     row vector will color each polygon (a column from matrices X and Y)
     with a single computed color.  A matrix C of the same size as X and
     Y will compute the color of each vertex and then interpolate the
     face color between the vertices.

this becomes ambiguous if size of each X, Y, and C is 3 because
C could also be an RGB triad ([ r g b]).

Dmitri.
