MATLAB: Most constrasting colormap for multi-line plots

Question

Hi everyone

I'm having a very frustrating time trying to get constrating colormaps for multiline plots.

For people with poor eyesight like me, it's very hard to tell the difference between the lines.

Here's an example using a very boring default scheme

x = linspace(0,1,101);
y(1,:) = x.^2;
y(2,:) = x.^2.2;
y(3,:) = x.^2.4;
h       = plot(x,y)
Colors  = get(h,'Color');
Colors{:}

What I'd really like, ideally, is an algorithm that delivers, for given n, a list of n colors that will have in some sense maximum pairwise contrast between colors. Doubt if this is possible, but any recommendations for something better than what I have would be most appreciated

Thanks for any advise

Have a look at these file exchange contributions: beautiful-and-distinguishable-line-colors, and generate-maximally-perceptually-distinct-colors

(Always search the file exchange before doing any work of your own, and way before asking others)
