The colors used by line plots are drawn from the 'colororder' property of the parent axes. By default, this is set to lines(7), so you'll only have 7 unique colors before it repeats.

You can set the colororder to any valid colormap:

set(gca,'colororder',parula(32))

... though you may find that it's difficult to distinguish between the lines due to the linearity of the colormap.

There are many colormaps available on the File Exchange that may be suitable for your needs, or you might try something like this:
