This is a fairly complex study concerned with limit-values defined no longer as elementary or primary but as antithetical: white and black, red and green, green and yellow. There is also antithesis between the round and the square. The center is constituted by the half-white and half-black circle inscribed in a square sub-divided into four further squares, two green and two yellow, alternated on the diagonals.
Round the square are four discs, half red and half green. The two colors, however, are arranged so as to suggest a rotation, as if the red was the side in the light, the green in the shadow, of a planet rotating on itself. It is know that, in the perception, white, yellow and red are colors which expand; green and black contract. In this way, in the image, an alternative sense of expansion and of blockage is achieved.
