Imagine Your rainbow panorama as an instrument that tunes you – its user – so that your body is transformed into a colour resonator. Enveloped in the rainbow environment, you produce afterimages in hues complementary to the colours in the glass panes around you. If you look at the city through red glass, your eyes develop a green afterimage. If you maintain a quick pace, the colours remain vibrant. But if you pause in one colour zone, the hue around you grows pale while the colours in your peripheral vision, where the walkway curves, intensify. Colour intensities depend on your speed.
