Plotting many plots on same figure with unique colors

Hi,

I am adding plots to a figure in my for loop as given below. I used 'Color' setting to define the colors. However there are only 7 options as per the ColorSpec given in MATLAB help. I may need to plot hundreds of plots in the same graph. How can I generate those many unique colors and then ask MATLAB to plot different lines in those colors?

colorstring = 'kbgrymckbg';
for  buscnt=1:Nbus-1
        for bw_combination=1:Ncomb
            if bw_combination==1          
                figure();
            end
                plot(x_plot,y_plot, 'Color', colorstring(bw_combination));
                hold on
        end
    end

Got it! There are some very useful files one may find in File Exchange.

I found both of these to solve my purpose :

and

At least the former one needs a toolbox unfortunately ...

The latter one works fine - thanks!

You can simply use any 3 element array of numbers between 0 and 1 to define whatever color you want. They don't have to be any of the specially named colors that use specific letters, for example

plot(x,y,'Color', [2., 3., .7]); % Use whatever numbers you want.

Thank you for your answer. The problem is that I need to do this within a loop and may need to plot hundreds of plots on the same figure. This may get a bit tedious. The two files posted earlier completely suit the purpose.

Moreover, it is important to avoid for example yellow, that is far too bright for white background.
