How to apply MarkerFaceColor in gplotmatrix?

Hi.

I'm trying to plot a set of matrices of size (16 x M). M changes, but 16 stays 16 (!). The gplotmatrix command does exactly what I need, except that I'm unhappy with the color specifications.

The 16 rows represent 16 groups, i.e. there is 1 point per group for each "subplot" in the gplotmatrix command. Since I want to keep track of which point is which across "subplots", they need to get some colors AND marker shapes.

Changing color and marker is no problem, BUT:

I want to use squares and circles as shapes, AND the colors need to be such that they are clearly visible, i.e. I want to fill the shapes with the repective colors. Strangely, I found no way to do this.

Adding 'MarkerFaceColor' to the input line of gplotmatrix gives an error ('too many input arguments').

Any ideas are highly appreciated.
