From now through September 12, upon entering the gallery Luxembourg & Dayan, which is housed in a townhouse on the Upper East Side, you will see a series of colorful paintings based on patterns of lace. Deeply beautiful, the paintings work well in the posh, pristine interior — they seem to fit their surroundings. On the wall just beyond them, you’ll see the title of the exhibition you’re viewing, which may not be quite what you expected, given all the abstraction and color and lace: “Mark Flood: The Hateful Years.”
