how to change mesh colorbar to appropriate colors?

I am making a mesh which has the folowing form:

     Z = varargin{1};%the values that will be meshed.
     C = del2(Z);
     h=mesh(Z,C,'FaceColor','interp','FaceLighting','gouraud')
     camlight right
     h2 = colorbar;

Using the camlight right the colors change from the original(shadowed) but the colorbar color remains if its like 'camligth right' is not used.How to shadow also the colors in in the colorbar?
