There are four colors - cobalt (seen here), amber (below), clementine (a bright orange) and turquoise. The binder holds the page protectors (which came in the large white box).
The little white box is what I think is fantastic. The page protectors I bought have four 4x6 spots - two at the top and two at the bottom - with four smaller spots in the middle. The pieces in this little white box fit in those spaces.
This very easily can be memory keeping for those who don't scrapbook while also being a starting point for those who love it.
Yes, the little white box is quite a financial investment (Thankfully, I had some Amazon gift cards to use), but if this system will get my pictures in a book and out of little paper envelopes, it's worth it!
