International Colour Day takes place annually on 21 March. An international colour day (ICD) Was first proposed in 2008 by the Portuguese Color Association, whose president, Maria Joao Durao, presented the idea to the International Colour Association. The proposal was agreed in 2009 among the members of this society, which is composed of national associations and members representing more than 30 countries.
Thanks to visual perception, Colour is one of the most influential phenomena in people’s lives and also one of the channels that contributes most greatly to the perception of reality. All around the world memorable colour activities are increasingly being developed during the International Colour Day.
Using The Date of the Vernal Equinox (March 21) for International Colour Day was suggested by Leonhard Oberascher Who pointed out that during the Vernal Equinox night and day are approximately equally long, symbolically relating to the complementary nature of light and darkness, light and shadow expressed in all human cultures. There was also an international competition for the design of the logo, and the winner was announced at the 2012 meeting of the International Colour Association, AIC 2012 held in Taipei, Taiwan. As expressed by designer Hosanna Yau, from 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.”
