I had a look at this too, Marina. I thought all the shades are a bit washed out by too much light in the video but it gives you an idea. There are also photos in this blog

And I found this quite useful on the QVC US website as (if it's accurate) you get an idea of which is more yellow, more pink, etc.

I did my own swatches of the Fair and Light in HydraLux and HydraGel foundations and there is definitely NO shade continuity throughout Doll 10. The two Fairs are completely different, as are the two Lights.
I don't know why I'm looking - I should be resisting!!
