color contour different then pcolor

I am using pcolor together with contour lines. However the value of the lines can no be identified from the plot, as can be seen in the following code

[x y data] = peaks(1000); 
data = data / max(max(data));
colorDepth = 1000;
colormap(jet(colorDepth));
hold on; 
pcolor(x,y,data); shading flat;
[C,hfigc] = contour(x, y, data,[0:0.1:1]);
set(hfigc, ...
     'LineWidth',1.0, ...
     'Color', [1 1 1]); 
hold off; 
hcb = colorbar('location','EastOutside');

I would rather want the pcolor to be in gray values and he contour lines in colors. However then I need a legend for the contour lines as well.
