From a New York Times story by Michael D. Shear headlined “With a Pocket of Shamrocks, Biden Celebrates St. Patrick’s Day”:

The first clue on Friday was the fountain in front of the White House, which flowed a bright, Kelly green.

There was also the green tie and the shamrocks in the breast pocket of the jacket that President Biden wore to greet Leo Varadkar, Ireland’s prime minister, or taoiseach, for his traditional visit on St. Patrick’s Day. Not to mention the confirmation of Mr. Biden’s visit to Ireland next month.
