figure;
axes('XLim', [-50 200],'YLim', [-50 200]);
line([0 172],[172 172],'LineWidth',5,'Color',[0 0 0])
line([172 172],[172 0],'LineWidth',5,'Color',[.1 .1 .1])
line([172 0],[0 0],'LineWidth',5,'Color',[.2 .2 .2])
line([0 0],[0 172],'LineWidth',5,'Color',[.3 .3 .3])

To compensate for line thickness, change it to:
figure;
axes('XLim', [-50 200],'YLim', [-50 200]);
line([-2 174],[172 172],'LineWidth',5,'Color',[0 0 0])
line([172 172],[174 -2],'LineWidth',5,'Color',[.1 .1 .1])
line([174 -2],[0 0],'LineWidth',5,'Color',[.2 .2 .2])
line([0 0],[-2 174],'LineWidth',5,'Color',[.3 .3 .3])

If you need nicer corners you should use patch instead of line. The syntax is similar, but you give coordinates of faces and vertices. You can also set transparency of patch objects.
