Frank Vincent DuMond (1865-1951) was an artist of great talent and a teacher of great influence. He worked as an illustrator for publications like Harpers, and he taught at the esteemed Art Students League of New York, where his students included Norman Rockwell and John Marin.

He also lived in Lyme, and he and wife Helen were founding members of the Lyme Art Colony.

DuMond’s work (and that of his students) is explored in an exhibition opening Saturday at the Lyman Allyn Art Museum. The name of the show is “The Prismatic Palette: Frank Vincent DuMond and His Students,” and the title reflects the part of the show that deals with color theory and DuMond’s way of mixing color strings, a method that other artists still follow.

“The Prismatic Palette: Frank Vincent DuMond and His Students,” opens Saturday and runs through Oct. 3, Lyman Allyn Art Museum, 625 Williams St., New London; hours 10 a.m.-5 p.m. Tues.-Sat. and 1-5 p.m. Sun.; $12 for adults, $9 for seniors, $5 for students, $7 for active military personnel, and free for kids under 12, for members and for New London residents; (860) 443-2545, lymanallyn.org.
