The “safety color” of the Japanese Industrial Standard (JIS) used for signs to prevent accident prevention and emergency evacuation has been revised for the first time in 13 years.
Everyone including those with impaired color vision becomes “universal design color” easy to identify, and the Ministry of Economy, Trade and Industry will spread to the 2020 Tokyo Olympic and Paralympic Games.
Safety colors set by JIS are used for signs such as “Red” Yellow Red , Yellow, Green, Blue, Red Purple – -” Fire Prohibited Prohibited “” Foot Warning “” Emergency Exit “. However, in the conventional definition, some people had drawbacks such as red being dark and misleading black, distinction between blue and green is difficult to distinguish.
Therefore, the committee made by affiliated organizations studied ‘easy to identify’ in two years.
As a result of examination, red and green were a little yellowish, yellow and blue were slightly higher brightness. In the survey for 132 people including amblyopia and color vision disorder, cataract people also felt “the difference in color is very difficult to understand” decreased from 11% so far to 3%.
In addition, in order to be widely used, JIS also set the recommended values for color designation on personal computer screen and printer output for the first time in case of fluorescence.
More than 3 million people with color vision disorder are said to be in the country, and about 300 million people in the world. Koichi Iga vice chairman of NPO corporation “Color Universal Design Organization” who participated in the selection said, “I am grateful as a party, I want to spread more and more and change the color of the world.”
