International Colour Day

The adoption of a worldwide day of colour was first proposed in 2008 by the Portuguese Color Association, whose president, Maria Joao Durao,[3] presented the idea to the International Colour Association (abbreviated as AIC for its French name, Association Internationale de la Couleur). The proposal was agreed upon in 2009 among the members of the AIC, which is composed of national colour organizations and members representing over 30 countries.[1][2]

International Colour Day was thereby established, with the 21st of March adopted as the official date. This date was chosen because it is around the equinox, when "the sun shines directly on the equator," and thus, the duration of day and night are approximately equal in length around the world.[4]

An international competition for the design of the International Colour Day logo was held at the 2012 interim meeting of the International Colour Association, held in Taipei, Taiwan.[5] As expressed by winning designer Hosanna Yau of Hong Kong, "two circles form an eye, with an equal half of rainbow color and black representing light and darkness, day and night, everyone feast one's eye on the international color day."

Some of the activities and events that are unfolded on the International Colour Day:

• Arts exhibitions, architectural projects, design, decoration, fashion[6]
• Meetings, debates, scientific events
• Workshops on the use of colour and light for both adults and children.
• Contests on colour and light design.
• Wearing national or regional identity colours.
