Red is the traditional shirt color of the South Korean national team, who are consequently nicknamed the "Reds", while the fans are called the "Red Devils". The away shirt has varied between white and blue. In 1994, the home shirt shifted from red to white, but in October 1995, red returned as home color, paired with black shorts.
Saudi Arabia secured qualification for the 2018 World Cup, their first in 12 years, ahead of Australia. In the opening match, Saudi Arabia were crushed by hosts Russia 5–0, making this the second largest victory of any host. Saudi Arabia then lost 1–0 to a Luis Suárez goal that put Uruguay as the eventual group winners. Although they were already eliminated, Saudi Arabia managed to salvage some pride by winning their final group stage match against Red Sea neighbours Egypt.
Traditionally, Saudi Arabia's home kit is white with a green trim, and the away kit is green with a white trim (the Saudi flag colors).
Japan uses blue and white rather than red and white due to a superstition. Japan first used blue shirts in the 1930 Far Eastern Championship Games, where a team of the Tokyo Imperial University (whose color is light blue) represented Japan wearing light blue shirts, and then in a 3–2 victory over Sweden in the first game of its maiden major international competition, the 1936 Summer Olympics. When Japan was coached by Kenzo Yokoyama (1988–1992) the kits were red and white, matching the colours of Japan's national flag. After failures at 1990 FIFA World Cup and 1992 Summer Olympics qualifications, the red shirt was scrapped.
Traditionally, Iran national football team's home kit is white, and the away kit is red. Sometimes, green shirts with white shorts and red socks are used.
