Colour and Chill 4, from Europrice, is the fourth and final volume in the anti-stress coloring collection featuring intricate, adult-style patterns. The Colour and Chill collection brings together intricate, adult-style patterns designed as an anti-stress activity: coloring slowly, without rushing, as a way to relax after a busy day. Europrice is the leading children's book publisher in Portugal, with a catalog designed to stimulate creativity and motor skills through pencil and paper, rather than screens. It's a great option to complete the collection with the final set of patterns, after having already explored the previous three volumes.
