People observe the colours of a day only at its beginnings and ends, but to me it's quite clear that a day merges through a multitude of shades and intonations, with each passing moment. A single hour can consist of thousands of different colours. Waxy yellows, cloud-spat blues. Murky darknesses. In my line of work, I make it a point to notice them.'
