The interactive non-fiction book "Wieso? Weshalb? Warum? junior: Welche Farbe ist das?" by Ravensburger invites children aged 2 to 4 on a colorful journey of discovery. On 16 pages in a handy 18 x 19 cm format, little explorers playfully learn about the colors in their environment. With an integrated turning wheel for mixing colors, exciting flaps, and partial die-cuts, learning becomes an active experience. Entertaining search and guessing games encourage close observation and promote color recognition and matching. Thanks to the sturdy spiral binding, this board book is particularly easy to turn through.
