International Colour Day

International Colour Day is held on March 21. The adoption of an international day of colour was 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. This event in the third decade of the month March is annual. Help us Help us 
21 March - International Colour Day
Worldwide blue is the most common favorite color. Due to blue's rarity in nature, it has a shorter history than other colors. Blue is not present in cave paintings from 20,000 years ago, and the Ancient Greeks did not have a term for blue. Ancient Egyptians valued the blue semiprecious stone Lapis lazuli, so blue became common in their language and clothing.
Men and women see the color red differently. Pink soothes the nerves and is often used for anger management. Yellow and red together make you hungry. While blue suppresses hunger! White Is The Safest Car Colour.
It was Isaac Newton who first fully developed a theory of color based on a color wheel. Newton had split white light into a spectrum by means of a prism and then wrapped the resulting spectrum around on itself to create the color wheel.
