Multi Surface Plotting & Color Control of each surface

My code, shown below, plotting two surfaces in the same figure functions properly.

%Plotting

figure(1)

[A1,B1] = meshgrid(X1, Y1);

Za = griddata(X1,Y1,Z1,A1,B1);

surf(A1, B1, Za)

hold on

[A2,B2] = meshgrid(X2, Y2);

Zb = griddata(X2,Y2,Z2,A2,B2);

surf(A2, B2, Zb)

grid on

title('Surface Plots')

legend({'1','2'});

set(gca, 'ZLim',[0 8.5])

shading interp

hold off

But I am trying to designate separate color patterns to each surface in the figure and no method I've tried works. Designating colormaps in various locations only colors all plots as the last color map declared and formating each surface plot with the surf(X,Y,Z,C) command hasn't worked with any of the color commands I know. Color map specifications or 'r', 'b', 'g' types.

Any other suggestions or if anyone has done this, I'd love some help?

Try setting the facecolor option using the RGB values. Here are a red [1 0 0] and a blue [0 0 1] surface, using built-in example data:

[X,Y,Z] = peaks(500); 
figure
view(3)
hold on

h1 = surf(X,Y,Z); 
h1.EdgeColor = 'none'; % gets rid of lines 
h1.FaceColor = [1 0 0]; 
h1.FaceAlpha = 0.8; % optional transparency 

h2 = surf(X,Y,Z+5); 
h2.EdgeColor = 'none';
h2.FaceColor = [0 0 1]; 
h2.FaceAlpha = 0.8; 
camlight % turns on lighting

I tried and it's still showing the default color map.

Can you provide a minimal working example that replicates the problem?
