Yellow. The colour of bananas, wasps, and post-it notes. Those among you who dabble in spectroscopy will know that yellow is the most luminous colour, demanding our visual attention more than any other. It’s not a colour normally associated with kicking back and zoning out, but with this design we’re attempting to redefine it in a more mellow way. With the help of a light gray background hue, the negative intensity has miraculously been drained away, leaving only thoughts of hammocks on the beach, sunshine, and psychedelic submarines. So slip these pups on, assume a horizontal position, and turn up Donovan’s 1966 classic to a relaxing volume. You’re now in the Mellow Yellow zone.
