The weekend paint attack on Denver’s Big Blue Bear will leave its mark at least until Wednesday.

Someone splattered green paint onto the back of the 40-foot-tall bear that peers into the Colorado Convention Center. The damage to the art installation — officially named “I See What You Mean” — was discovered Sunday morning.

Bad weather through Tuesday and the ongoing police investigation will stall restoration of the sculpture, which was installed in 2005.

“We expect weather to get pretty crummy,” said Denver Arts and Venues spokesman Dan Rowland.

Weather permitting, a maintenance crew will take care of the bear Wednesday.

“I think it’s a latex-based paint,” Rowland said. “It should be fairly simple to clean up.”

Incidents like this are rare among the nearly 100 pieces of public art in the city, Rowland said.

“Most people leave stuff alone,” he said.

Denver police spokesman Aaron Kafer said investigators have not identified a suspect.
