It is well known that the three primary colors RED, YELLOW and BLUE can be mixed to create an infinite number of colors. With the Colouring Puzzle by Siebensachen, the whole color variety of the color wheel can be joyfully recreated. Piece by piece the various color shades assemble creating a fluent transition as each mixed color becomes visible: Between red and yellow lies ORANGE, between yellow and blue lies GREEN and between blue and red lies VIOLET. These are the secondary colors. An infinite amount of color possibilities lies in between. 96 pieces. 13″ diameter. Designed by Adam + Harborth, Berlin.
