Colour C'clock changes hues as time passes

Colour O’Clock by Duncan Shotton complements the passing of time with color. The all-white, wall-mounted timepiece includes a rounded window at its base, which subtly shifts through the full chromatic cycle gliding through greens, purples and blues in a continuous drift. As the seconds, minutes and hours roll steadily by, the color window glides subtly through the full spectrum of colors, creating a timepiece that adds a more relaxed method of reading the time, not by number, but by color.
