specific RGB color in plot3

I want to use the gray color in the function 'plot3'.

I currently use this to apply the black color:

plot3(A(:,1), A(:,2), A(:,3), 'k.','Markersize',5);

Since the figure is composed of nodes of x,y,z coordinates, I tried this way but it creates gray lines on the 3D figure:

plot3(A(:,1), A(:,2), A(:,3), 'Colors', [0.7, 0.7, 0.7],'Markersize',5);

A=randi(100,10,3);
%Marker size 5 is a bit small for a good visual
plot3(A(:,1), A(:,2), A(:,3), 'LineStyle', 'none', 'Marker', '.',...
    'Color', [0.7, 0.7, 0.7], 'Markersize', 7)
