Watercolor paintings are usually translucent, giving the viewer a peek into the process. All it takes to amaze is to look at works by well-known artists who specialize in the medium, such as Winslow Homer and Georgia O’Keeffe. It’s so popular that the American Watercolor Society was founded as early as 1866. We have some excellent watercolorists locally as well. Cathy Hillegas, a painter from Floyds Knobs, began taking classes in 1993. The student is now the master, teaching watercolor at the Arts Council of Southern Indiana in New Albany. Two of her paintings have been published in the “Splash” series of watercolor books. The opening reception at Chestnuts and Pearls art gallery and café is Thursday, April 27 from 6-9 p.m.
