Paint the town Orange and Blue!

Queens Borough President Melinda Katz and the Mets organization will host a Hometown Rally at Queens Borough Hall on Monday — the day before Game 1 of the World Series — to cheer on the Amazins’ bid to bring the championship trophy back to Flushing and the Big Apple.

The rally will take place between 3 p.m. and 5 p.m.

The event will feature family-friendly activities, food and beverages. Blue and orange attire is strongly encouraged.

“The World Series is coming back to the `World’s Borough.’ Congratulations to the Mets on their sweeping victory in the National League Championship Series. The Mets have done all New Yorkers proud, redeeming millions of loyal fans and even inspiring a few more,” Katz said.

“The Amazins played with true grit, determination and heart – trademarks of every New Yorker – in clinching their first National League championship since 2000. New York is united as one sea of blue and orange behind the Mets in this captivating run. Ya Gotta Believe – now Let’s Go Mets!”

The Mets won the World Series trophy in 1969 and 1986. They last appeared in the Series in 2000, when they lost to their crosstown rivals from The Bronx, the Yankees.
