WHAT IS ICD?
The INTERNATIONAL COLOUR DAY was established by the AIC – International Colour Association. Celebration of the international day of light and colour on March 21st has spread throughout the AIC international network and is now supported by its members all over the world.
ICD – International Colour Day – was considered an appropriate recognition since, thanks to visual perception, colour is one of the most influential phenomena in our lives and is also a major contributor of our perception of reality.
Since light and colour are inseparable, ICD – International Colour Day – celebrates colour as well as light. Colour is always connected with light; without light there would be no colour.
Few things affect us as much as colour. It plays a vital part in the perception of our surroundings, whether at work, in public spaces or in our homes. Colour and light are such universal components of our existence that we don’t usually even give them a thought. All surfaces are coloured. Colour has an outstanding role in our society and it also tells us much about different cultures, being a crucial aspect in the ways we define our identity.
WHY MARCH 21st?
The proposal to establish an international colour day was made in 2008 by the Portuguese Colour Association – Associação Portuguesa da Cor APCOR – whose president Maria João Durão presented the idea to the International Colour Association. The proposal was approved in 2009 among the members of the AIC society, which is composed of national associations and members representing more than 30 countries.
The choice of date came after a good deal of discussion. Among all suggestions presented, the idea exposed by Leonhard Oberascher from Austria prevailed: the Spring equinox – aequus (equal) and nox (night) occurs around March 21st.
Around the equinox, night and day are approximately of equal length, symbolically relating to the complementary nature of light and darkness, light and shadow having their expressions in all human cultures.
LOGO
An international competition was held for the design of the logo, and the winner was announced at the meeting of the International Colour Association, AIC 2012 held in Taipei, Taiwan. The selected design was created by Hosanna Yau, from Kowloon, Hong Kong.
As expressed by designer Hosanna Yau: ”The two circles form an eye, equally combining the colours of the rainbow and black, representing light and darkness, day and night – everyone feasts one’s eye on the International Colour Day.”
The logo can be downloaded for use from the AIC website.
