Colormap with "hold on" on one axis

I have such code:

h=trisurf(triB, x, y, z, 'FaceAlpha','0.8');
hold on
h1=trisurf(triS, x1, y, z, 'FaceAlpha','1.0');
axis vis3d
shading interp

I would like to use two diffrent color maps for h and h1.

h and h1 do not have the same size in any of x, y or z axis; h is a big ball, h1 is also a ball but smaller and inside of the biger one(h).

How can I do that?
