Different color for every point - Scatter3

Hello,
I'm using the function Scatter3 to plot a variable number of points (I use the function getpts to click on an existing plot and get the points), for example a 2x4 matrix (x and y coordinates). As I said, it's variable depending on how many times I click, so it could also be a 2x1 or 2x5 (etc) matrix. Then I use this points to draw them on another scatter3 figure.
It would be tremendously helpful if I could have every point have a different color, it doesn't matter which. It would help me determine where each point is plotted on the other figure.
Can you help me figure this out?

One Way: Sample data example is taken from MATLAB docs
[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(:)];
figure,scatter3(x,y,z);
% Now plot the same with different colors
figure;
for i=1:length(x)
plot3(x(i),y(i),z(i),'o');
hold on
grid on;
end
