Apply a specific RGB color on plot3

Hi. I have this code.

selection = importdata("selection.mat");
figure
plot3(selection(:,1),selection(:,2),selection(:,3),'b.','Markersize',5)
grid on
hold on
axis equal
xlabel('x')
ylabel('y')
zlabel('z')

I would like to apply a certain color (in this example, blue) to the nodes using an RGB value, for example like this:

plot3(selection(:,1),selection(:,2),selection(:,3),'Color',[0,0,1],'Markersize',5)

plot3(selection(:,1),selection(:,2),selection(:,3),'.','Color',[0,0,1],'Markersize',5)

ok, thanks!

plot3(selection(:,1),selection(:,2),selection(:,3),'.','MarkerFaceColor',[0,0,1],'Markersize',5)

There is also MarkerEdgeColor. For the '.' marker, whether you use Face or Edge seems to affect the shade of blue used, and I am not sure why that is. For some styles of markers it is important which one you use; 'Face' color corresponds to asking for 'fill' on the markers, but some markers are only defined in terms of edge.
