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).
