Happy 140th birthday, Colorado.

Dunkin’ Donuts wants to help you celebrate.

The East Coast-based chain is offering a limited-edition doughnut frosted like the Colorado flag Aug. 1-7 at Centennial State locations.

The Colorado flag doughnut is free with the purchase of any size Cold Brew Coffee, or it retails for 99 cents.

"We are grateful to all the Coloradans who have welcomed Dunkin’ Donuts into their communities,” said Lou Conte, Dunkin’ Donuts Colorado field marketing manager, in a written release.

There are four Northern Colorado stores among the participating branches: Fort Collins, Windsor, Loveland and Longmont.

Dunkin’ Donuts has 23 Colorado locations participating in the promotion.

Dunkin’ Donuts returned to Fort Collins in October 2014, with the other Northern Colorado locations following soon after. Previous locations in the area closed in the 1990s.
