With wood floors and slate walls, David Findlay Jr. Fine Art in the Fuller Building is, like many galleries, a blank canvas. A new exhibit showcasing the abstract expressionist paintings of Chuang Che, Carl Heidenreich, and Emily Mason, splashes that canvas with color. The show opened Saturday with an afternoon reception that drew artists, collectors, and dealers.

The exhibit is comprised entirely of works on paper — drawn, and painted in charcoal, watercolors, acrylics, and oils. “They’re dealing with light and color,” the gallery’s director, Louis Newman, said of the artists. “They do play off each other.” Before he started preparing this show, “I had never heard of Heidenreich,” Mr. Newman said. “He had this wonderful career, and after his death [in 1965] became less visible. So we’re trying to correct that and bring him back and make people aware of his contribution to modern art.” Mr. Che, a pioneer of modernist art in Asia, has had work on display at the National Museum of History in Taipei, the Hong Kong Museum, and elsewhere. Ms. Mason, whose work is grounded in the abstract expressionism of the 1940s and ’50s, is inspired by nature. Her last solo show at Findlay was in 2005.

This is the first show Mr. Newman has staged comprised entirely of works on paper. “Other cultures, especially Asian, have a great appreciation for paintings on paper,” he said. American artists, he added, “put maybe a little too much emphasis on canvas.”

Spaced evenly on the walls, pieces like Heidenreich’s “Abstraction IX” (c. 1950s), with swirling red and blue charcoal and watercolors, hangs near Ms. Mason’s abstract landscapes and Mr. Che’s oils and acrylics. Sitting on a bench before a wall of her father’s art, Monica Heidenreich Smith said she had never before seen these particular works.

In the gallery’s side room, the Los Angeles art dealer and radio personality Molly Barnes held court. “We all own Milton Resnicks and Herman Cherrys,” she said, referring to the late abstract expressionist painters, “so this is a special room.” She sat with Cherry’s widow, Regina, and their friend Una Dora Copley, whose parents, the artists Alfred L. Copley (known as Alcopley) and Nína Tryggvadóttir, first met in the Fuller Building more than 50 years ago. Ms. Copley is a frequent visitor to the gallery, and said she enjoyed the juxtapositions in the exhibit.

The dealer Calvin Goodman, who has known Mr. Newman for more than 40 years, chatted with the artist Susan Sommer. Ms. Sommer said she loved the exhibit. Asked if she had shown her work at the gallery, she laughed and said, “I’m too young. I’m glad there’s something I’m still too young for!”

In the main gallery, the large crowd included the German consul general, Hans-Jürgen Heimsoeth, and his wife. They mingled near Mr. Che, who was visiting for the day from his home in Yonkers. He said he became an artist at 7, drawing inspiration from classic Chinese style. Mr. Che had a solo show at the gallery in April that incorporated three-dimensional pieces. Before the show, he knew Ms. Mason’s work well but was not familiar with Heidenreich’s work. “This is the first time I’ve seen it,” he said. “I think it’s great. He uses soft, rich colors.”

As the party came to a close, Mr. Che was approached by a woman who said she was a recreational painter. “You’ve inspired me to go home and practice,” she said.
