    • A learning toy based upon the concept of design or pattern formation is disclosed. The toy is comprised of a tray having a transparent bottom and a plurality of blocks which are arrangeable in the tray to form a design or pattern. Each block is painted with a primary color on four of its surfaces while the fifth surface of the block is painted with two of the primary colors with the boundary therebetween being on a diagonal across the surface of the block and the sixth surface of the block is painted with the other two primary colors with the boundary therebetween being on a diagonal across the surface of the block. When the blocks are arranged in the tray to form a design or pattern, a juxtaposition of dark and light colors is created on the top surface of the blocks and an “opposite” design or pattern is formed on the bottom surfaces of the blocks which can be viewed through the transparent bottom surface of the tray.
