I recommend to parents to purchase as soon as your child at 18 months which allows him to become familiar with the colors ... As for my 20 month old son does not understand the colors, it is simply fix or fish, pig, etc., without knowing if it's pink or red ... I think he will know his color in a few months Drawings (paw-tone photographed) from this collection are very beautiful and well resemble reality Downside: the price as always, we would like a little more inexpensive (less than 4 Euros would be perfect)
