The color is exactly displayed in the Natura like here. The leatherette really feels pleasant, very soft and pliable (I hope it is durable and robust even in the long run - but that will only become clear over time). The brown inside also feels good and looks nice. Overall, I like the whole style very well and also the workmanship is great - there's nothing to complain about.
But the shell has been designed for the Kindle Touch (as it is at least on the packaging) and not for the Sony Reader. The Sony Reader is too thin (or alternatively too narrow) for this envelope so that the retaining tabs are not applied, reasonable. He can not fall out, but the bottom tabs to wrinkle and cover the operating part - I thought that was really extremely annoying!
Because my sleeve but otherwise like so much, I have the Sony Reader lined with a thick envelope: by the retaining tabs finally sit tight and even the controls are barely concealed. However, the whole thing becomes a bit wider and heavier. Had I known that before, I would probably rather buy my Gecko-shell (available but only with snap closure tab and not with the rubber band).
So: the shell itself is great, you improvise but definitely for the Sony Reader must. Who does not want to improvise, the better buys another envelope. I'm happy but really disappointed by my modification to the shell of the now fit. So you also see what I have tried to describe here, I have a few photos set - I hope I have helped you in your decision for or against this shell; o)
