Color is one of Mother Nature’s most useful messengers. Even black-and-white works of art somehow appear more vibrant because our visual sense “imagines” their contrast with full color. The “New Color Messages” exhibition exemplifies and caters to this human faculty. It opened Saturday at the 555 Gallery on Second Street, and is jointly curated by John Rizzo, most recently in Portland, Ore., and 555 Gallery owner Susan Nalband. Be sure not to miss this joy-filled show, especially now that spring seems to be at hand.

The gallery at 555 East Second St. is open Tuesday through Friday from 10 a.m. to 5:30 p.m. and Saturdays from noon to 5 p.m.

Works shown in photos: “Domestic Bliss” by Patty Carrol, “Tree Lines” by Mary Ellen Strom, “Storm Clouds over Boston Harbor” by Jeffrey Heyne.
