Is the Rinnegan completely purple in Naruto?


This is probably a really stupid question, but is the Rinnegan completely
purple from the front to back, or is it just the iris that's purple? Pictures
would help.




In this [link](http://naruto.wikia.com/wiki/Rinnegan) there is one statement :

> The Rinnegan is characterised by a **ripple pattern that spreads over the
> eyeball**.

Since it spreads over the eyeball then in conclusion we can say that it is
completely spread from front to back as it covers the whole eyeball.

Also there is no evidence which proves that Rinnegan purple color is limited
to that pupil area only.
