Art show raises awareness of mental illness

Levi Detwiler is after the perfect shade of pale turquoise. He swirls together the ingredients — a “calming” blue, some white, a dollop of green — on a paper plate, looking for a color to accent his canvas, a black tree fanning over an ocean-like swirl. A few tables away, Dolores Aderman is too engrossed in her painting — a still life of flowers by a windowpane — to look up. She’s trying to finish the painting on a tight schedule, and there’s still a vase and speckled sky to draw.
