the color of the square depends on the colormap of the axis. Try
ax = gca;
ax.Colormap
by default colormap is
0.2422 0.1504 0.6603
0.2504 0.1650 0.7076
0.2578 0.1818 0.7511
....
....
0.9691 0.9606 0.1064
0.9769 0.9839 0.0805
These are RGB colors. The value in your matrix M, along with the colormap and clim property of axes object which color will be displayed. For more information, refer to the properties of MATLAB axes object and search for Colormap and CLim.
