How do I make colors for scatter3 same as in Stata graphs

I have data that I visually represent using Stata and using MatLab. I have seven colors in the Stata graph, corresponding with seven groups. I would like to use the same colors in the MatLab graph I create with scatter3d. How?

You can pass a 3D matrix of RGB values to scatter3 function as in following example,

[X,Y,Z] = sphere(16);
x = [0.5*X(:); 0.75*X(:); X(:)];
y = [0.5*Y(:); 0.75*Y(:); Y(:)];
z = [0.5*Z(:); 0.75*Z(:); Z(:)];

S = repmat([50,25,10],numel(X),1);
C = repmat([1,2,3],numel(X),1);
s = S(:);
c = C(:);

figure
scatter3(x,y,z,s,c)
view(40,35)
