Wales supporters will wear rainbow bucket hats and hold rainbow-coloured scarves aloft at Ahmed bin Ali Stadium for their World Cup match against Iran after the country's FA received permission by FIFA to do so.
The deal relates specifically to the FA Wales and FIFA.
The FAW reached out to the governing body to allow their fans to sport the colours. Rainbow-coloured bucket hats are particularly popular among the fanbase, with reports some people have had them confiscated by officials in Qatar, where homosexuality is illegal.
FIFA rules ban "political, religious or personal messages or slogans", however they have relented in this instance, with the FAW confirming in a statement: "In response to the FAW, FIFA has confirmed that fans with Rainbow Wall bucket hats and rainbow flags will be allowed entry to the stadium for Cymru's match against Iran on Friday.
"All World Cup venues have been contacted and instructed to follow the agreed rules and regulations.
"The FAW urges FIFA to adhere to their message that everybody will be welcome in Qatar during the World Cup and continue to highlight any further human rights issues. We remain with the belief that football is for EVERYONE."
There has been much tension over FIFA's insistence that players do not wear 'OneLove' armbands, which are intended to send a message of tolerance, connection and opposition to all forms of discrimination.
Instead they offered team captains an armband that says 'No Discrimination'.
FIFA threatened several European team captains with yellow cards if they wore them to support LGBTQ people in Qatar.
In protest, Germany players placed their hands over their mouths during a team photo ahead of their game against Japan.
