The former Lord Mayor of Dublin has called on the capital's households to decorate their homes with blue-and-navy flags ahead of Sunday's All-Ireland Football Final.
Christy Burke is calling on Dubs to turn the city blue and navy as the county's footballers prepare to take on Kerry for the Sam Maguire trophy.
"I would ask people to decorate their homes in bunting and flags to show their support for the Dublin team as they gear up for the big game on Sunday.
"It would be great if businesses could get involved as well, to show the team that their county is really behind them," Mr Burke said.
The north-inner city councillor has also contacted Dublin City Council about the possibility of lighting up the Liffey ahead of the All-Ireland final.
It is hoped that lights attached to several bridges along the quays will be turned blue and navy, and be reflected along the river.
"I have contacted Dublin City Council and it is hoped that the River Liffey can be lit up in the county's colours ahead of the game," Mr Burke said.
The Mansion House will also be illuminated in blue and navy colours at the weekend. Lord Mayor Criona Ni Dhalaigh has also called on the city to be turned blue for the mammoth occasion.
Ms Ni Dhalaigh is hoping the whole city will get behind Jim Gavin's team on Sunday.
"I've put a request in to see what other things they can do ahead of the game," she previously told the Herald.
"I'd like the idea of the whole of Dublin being covered in blue for the match - so there'd be no getting away from the fact that you're in Dublin and that Dublin are playing in the final.
"The Mansion House is already lit up, all blue, and the flags will be up soon, too," Ms Ni Dhalaigh said.
