How to plot curve with one color without precising which color it is?

How can I plot curves with the same color without having to determine exactly what color I want? The plot function is inside a for loop and for each iteration I want to have a group of curves with the same color.

for i = 1:10
    if i == 1
        h = plot(1:10,1:2*i:20*i)
        v = get(h,'Color');
    else
        plot(1:10,1:2*i:20*i, 'Color', v)
    end
    hold on
end
