what is the significance of Purple and green color icons for portlets ?

All the portlets with a green icon are instanceable portlets. This means you can have
multiple instances of this portlet on a page and within a community or organization and each
of the instances can hold different data.


Portlets with a purple icon are non-instanceable portlets, meaning you can only have
one instance of this portlet across an organization or community. You cannot add this
portlet more than once to the page. Also, they share the same or common data within the
organization or community that they are in.
