How can I produce colours to distinguish between points in a plot?

Hi all,
I am wondering how can I produce extra colours to use them in a plot. For example, I want to have extra colours more than what I have here in an array.
color = 'rmcgyk';
Each letter corresponding for a colour but for my purposes, they are not enough!
Is there a way to have more?
Thank you

Sure, you can define colors through their (normalized) RGB values, e.g. [ 0 0 0 ] is black, [1 1 1] is white, and then you can choose anything in between. There are also lots of color-generators around like
On a side-note: There are tons of options for the plotting functions, just check out the documentation (type "doc plot" into matlab).

You can do
plot(x, y, 'Color', [r, g, b]);
Where r, g, and b go from 0 to 1. If you want that to happen automatically, see my color order demo, attached below the image.
