It is about the compositional relation of the black. There is no need to discuss the calculated outcome and the nuance of the black at this point. The discourse should be about the character of the edges where the black wall isolates itself from the light. The light, as it gets paler, evokes the fierce emotion to resist against it.
This is neither about the philosophy of Anish Kapoor nor the transcendent world of 'void' and 'creation'. By the solidness getting desaturated and the nothingness being arranged in the space, the meaningless lines, fragmented surfaces and random orders make the blackness even more vivid. The metaphor, a space full of comprehension that only exists to be comprehended brings silent nihilism to the boredom design.
