International Colour Day – March 21, 2025

International Color Day is celebrated every March 21, and we are going to show you how you can celebrate the day. Do you know that it has been 14 years since the idea for International Color Day was proposed by the Portuguese Color Association? International Color Day was created to celebrate color. The date was chosen as March 21, as it is the day of the equinox, which means the lengths of day and night are almost the same as the sun’s rays are straight on the equator. This day is celebrated by setting up exhibitions, science shows, and interactive programs for children, among other activities.

History of International Colour Day

Color has always made humans curious since the beginning of time. Aristotle believed that the colors came from heaven. He believed that the origin of all colors was black and white. However, it was in the 1660s when Issac Newton experimented with light and its different spectrums, that color became a topic of study. After 2000 years, Aristotle’s postulates were replaced by the ones Newton created. Johann Wolfgang von Goethe, a German novelist, playwright, and scientist argued that color was something that was perceived by individuals differently. He is well-known for his quote, “Colors are light’s sufferings and joy”. The distinction between primary and secondary colors was made by Jacob Christoph Le Blon.

In 2008, Maria Joao Durao, the president of the Portuguese Color Association, came up with a proposal to ‘Association Internationale de la Couleur (A.I.C.)’ for recognizing the importance of color and dedicating a day to it. In 2009, the proposal was accepted by the members. The date was chosen to be March 21 as it is the day of the equinox. Competitions, science fairs, art fairs, etc. are held to celebrate. In 2012, an art competition was held in Taipei, Taiwan for deciding on the logo for International Color Day. Hosana Yau of Hong Kong won the competition with his diagram of two circles that made an eye. Half of the circle consisted of rainbow colors and the other half was black. They represented light and darkness.
