A tour across Lucy Vincent Beach, painted in the winter in utter abstraction, is a riot of reds and yellows and greens where some might have only seen white. The ubiquitous tower, done in gold, juts up in an uncertain rectangle. Wendy Weldon’s latest collection of acrylics on board on display at North Water Gallery is plucked from her beach walks with her dog Lillie Belle, a two-and-a-half-year-old mutt.

“I have to say the election put me in a place as a painter that was very dark, I needed to figure out how to get out of that uninspired place,” she said at the opening reception on Thursday. “Every morning or afternoon, my dog and I would go to the beach.”

While walking on Lucy Vincent, looking at the clay formations, she said the thought occurred to her, “this is not always going to be there.”

So she began to paint it.

Ms. Weldon, who identifies with the abstract school of art, may be recognized for her barn paintings, simple rectangles and squares topped with triangles in rubied reds, greens and yellows. Some are imagined and some are plunked down into fields that do exist.

At least one of those barn paintings hangs at the beginning of the show, to mark where the viewer is to start, before tumbling into the abstract forms of the up-Island beach. The final paintings, the most abstract, embrace drips that slide down the canvas.

“I did, I let the paint drip,” she said to a woman in conversation at the reception.

Robin Nagle, gallery director, spoke about Ms. Weldon’s bold use of color and the energy that imbues her work.

“This is not a still, calm show,” she said.

Alongside Ms. Weldon, Craig Mooney and Brandon Newton exhibited their work as well.

Mr. Mooney’s imagined landscapes may be of serene locals, dipped in romanticism, but their energy is boosted by an explosion of light bursting through textured clouds, radiating in reflection on the water.

Mr. Mooney said he paints familiar landscapes that are purposefully unidentified.

“They are familiar without being specific,” he said. The artist compared it to not quite knowing the lyrics to a song, but filling in words anyway. He thinks there is more satisfaction in the mystery and usually disappointment in the answer. He recalled thinking the line “over seas of silence” in Sting’s Why Should I Cry for You was “over caesar salad.”

Brandon Newton’s watery paintings of night scenes, down a road or near a harbor glisten with jewel tones, warm windows and dark corners.

“I’ve gotten into a ruby palette lately,” he said, gesturing to a painting of the Edgartown harbor during sunset. “It’s very energetic, very lively.”

Even as they hang on the gallery wall, Mr. Newton doesn’t see his paintings as quite finished.

“They are not completed until they are hanging on someone’s wall in their home,” he said.

The show for all three artists will stay up through August 31.
