Grimms have translated the Four Temperaments into a language of form and colour. The result is a colourful building set with 61 building blocks in free form. The individual building blocks are reminiscent of animals and various other creatures, and by combining different building elements, something new is always created that will stimulate and inspire the imagination. The predominant temperament determines the specific mood in which someone usually finds themselves. It influences how we feel and experience life, how we think, act or react. The Melancholic temperament has a compassionate and rather sad nature. It is BLUE, turning inward into the depths, with edges, curves and endurance like its element, the Earth. The Choleric temperament has an active and fiery nature. It is RED, jagged and sometimes sharp edged. Its impulsiveness belongs to the element of Fire. The Phlegmatic temperament is steady and content. It is GREEN and still like the surface of a pond. Its curves and soft shapes correspond to its element, Water. The Sanguine temperament radiates cheerfulness and optimism. It is YELLOW and shines from within, losing itself in the periphery or in the sky. Air is its element. Through a playful approach to the characteristic features of the temperaments, a feeling for their essence can be developed. Each person is a unique blend of all Four Temperaments. 61 building blocks in wooden frame, incl. paper template in original size.
