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
