Designer Oscar Diaz has created the Ink Calendar, which makes use of a timed paced ink reservoir that leaches onto a paper calendar to indicate the date. The ink is absorbed slowly, and the numbers in the calendar are “printed”, or otherwise coloured on a daily basis. One a day, they are filled with ink until the end of the month. The calendar enhances the perception of time passing and not only signalling it. The aim of the project is to address our senses, rather than the logical and conscious brain. The ink colours are based on a spectrum, which relate to a “colour temperature scale”, each month having a colour related to our perception of the weather on that month. The colours range from dark blue in December to three shades of green in spring or orange and red in the summer.
