* Edits: Sorry for the wrong information about the default line color.
Otherwise, you can try
figure
hold on
randColor = rand(10,3);
for i = 1:10
plot(x(:,i),y(:,i),'Color',randColor(i,:));
end
legend
But the color would be ugly. Instead of rand, you can try other available colormap. For example
figure
hold on
cm = parula(10);
for i = 1:10
plot(x(:,i),y(:,i),'Color', cm(i,:));
end
legend

You can make a cell array for each color you want and the pull from it
colors = {['red'],['blue']}
for rep = 1:2
plot((x,rep.*x), colors{rep})
end
This will plot two lines, the first red and the second blue
