With the many books on the market aiming to help our young ones learn their colours, which is the best? An impossible question to answer, but this book from the excellent Dorling Kindersley range really helped our young lad, at about age 2 to 3.
This is a wonderful starting point for your young one(s)to discover the world of colour. There is no ambiguity with this book, as all colours are easily identifiable, with even a "multicolour" double page at the end. As this is a board book, it is pretty robust as well.
No pressure - just let the kiddies enjoy the book, and everything will come in its own time.
