my program to convert from RGB to XYZ and draw those pixels on my 3D space is not working, when I run it, no pixels appear at all, can you give me the direction of the resolution?, thanks!

my code

% generate two clusters of color points
rgb = min(abs(randn(1,3).*[68 200 200] + [0 0 0]),1);
rgb = [rgb; 1-rgb];
xyz = rgb2xyz(rgb);
xlabel('X');
ylabel('Z');
zlabel('Y');
hold on;
% plot the points
scatter3(xyz(:,1),xyz(:,3),xyz(:,2),100,rgb,'.');
view(3); grid on; 
axis equal
axis([0 255 0 255 0 255]);
set(gca,'color','w','gridcolor','w','gridalpha',0.3)
set(gca,'projection','perspective');
