So Nathaniel and I asked, and the blog post author, Steve Eddins, took 
the time to answer :

    Nathaniel and Pierre—Thanks for your interest in the new parula
    colormap. /Parula is the end result of a creative design effort over
    an extended period of time. I am pleased that you find it so
    appealing. The colormap is, however, MathWorks intellectual
    property, and it would not be appropriate or acceptable to copy or
    re-use it in non-MathWorks plotting tools./

    You might look at other sources of high-quality colormaps. I have
    listed some in my technical paper on rainbow colormaps, published
    earlier this month on mathworks.com.

So they claim the IP. Next question is: is this claim valid, and I'm not 
a lawyer to answer it. I suspect that the answer could be country specific.

The only things that bother me in this IP claim, is the status of all 
the plots produced with this colormap. They are in a sense a 
/derivative/ work, am I right ? So the question becomes : does Mathworks 
owns IP right for all these plots ?!
