"Colhour is a system for visualising time, based on the spectrum of the rainbow. Every variable in the clock - second, minute, hour, day, month and year - cycles through the colors of the spectrum which begins with the color purple. However, the most important aspect is not that all the variables are represented – an application of Colhour could aswell only include the seconds or a combination of a couple of the variables" via harald.net
