Their latest jersey has been revealed online by Simon Cox - and shows a big deviation from the traditional green and white.
And the colour is sure to be matched by the mood of football fans who are being asked to shell out €60 for the jersey - a year after the old one was unveiled.
The FAI launched the white away top in the lead-up to Euro 2012 in Poland last year.
But a replacement has already been designed and manufactured and could be in the shops within weeks.
However, it's certainly not as controversial as the orange Ireland kit released in the late 1990s, which was universally panned at the time.
The current Northern Ireland away top is black, while the IRFU unveiled a black away jersey for the international rugby team last November.
Nottingham Forest and Republic of Ireland international Simon Cox posted a photo of the new jersey online.
"So what do you all think of the new Ireland away kit? It's pretty slick," he tweeted.
The national team donned the previous away kit, unveiled in February last year before the Euros, in only two competitive games.
No date yet has been given for the launch of the new kit. Ireland's next away game is in Sweden on March 22.
