Hi Julia,
Thank you so much for your review. Yes you are right, our polka dot print has a natural ivory white finish vs pure white which we thought would be too harsh. This was an intentional design choice and is seen on our website in the close up detailed shot of the play mat. In some lights it reads more cream and in other lights reads as more of a soft white.
On the other hand, the white on the Geo - is a pure white as it is a smaller area and we thought would be balanced well by the black and grey :)
xo love you to pieces
