Contributed by Sharon Butler / This month, don’t forget to look up and admire the trees, which are having the last gasp of color that I’ve always thought is impossible to paint (or photograph) without seeming hopelessly sentimental. Meanwhile, in the galleries, check out “Big Little Color,” an elegant abstraction show at Carrie Haddad featuring geometry, pattern, and sophisticated color. Ashley Garrett, Charlie Goering, and Evan Halter are in “knowing when,” a group show at Turley Gallery that celebrates knowing when to ignore the internal voices and listen, and knowing when to stop. At LABspace Susan Carr is back for another outstanding solo with new work that continues her exploration of, and search for, happiness. And finally, don’t miss “The Material, The Thing,” a big survey of talented Hudson Valley artists at the Dorsky Museum. It’s only on view through November 6.
