Oil and water normally do not mix, but the exhibit titled "Oil and Water" is a smoothly integrated display of oil paintings and watercolors at the Bernice Kish Gallery at Slayton House. This show consists of works by Brenda Will Kidera and students at her studio in Woodbine.Kidera generously devotes this exhibit almost entirely to her students, but her own exhibited work includes a large watercolor, "Something Old, Something New," which sets the bar high in terms of technical achievement. This watercolor depicts a woman whose pink-and-white formal dress seems all the more elegant owing to the light shimmering across its surface. The elegance of the portrait also is enhanced by the woman's pearl necklace and a white glove. Her downcast eyes and pensive expression make this portrait seem reflective in more ways than simply how the light plays across it.Kidera's students have work in various genres. Among the landscape subjects on view, it's seasonally apt that some of them reference the fall season that more or less has been upon us in recent weeks.Nancy Jean Davis' watercolor "Fall Colors" features a forest in which some trees have leaves that are turning red and other trees that are still holding onto their green leaves. Besides noticing these color distinctions in the forest, you are able to have a look at the forest's reflection in a body of water.For a more detailed consideration of this leafy subject, Susan Donoughue Britt's watercolor "Floating Leaves" showcases leaves whose various shades and vein-like markings are set against a deep brown background.Moving into a season that many of us would rather avoid, Janet Arsenault's watercolor "Winter Creek" depicts the snow-covered ground beneath nearly bare trees. What's especially notable here is that the snowy ground is hardly flat. Instead, it has assorted ripples and bumps indicating whatever organic matter rests beneath the snow.Natural imagery predominates in much of this show, and some of the wildlife is close to home. Karen Schuster's watercolor "Hungry Mockingbird at Wilde Lake," for example, features a bird perched on a branch. It's evidently happy considering how eagerly it chomps down on a red berry.Not only do animals interact with the natural world that supports them, but people also do so in various ways. Nature has been harvested and awaits human purchase, if you will, in Kathleen Junker's watercolor "Flower Mart at Market Square." A single shopper has a wealth of choices to make admist a profusion of cut flowers and live plants at a market stand.Nature also has a starring role in some of the still-life subjects in this show. Juanita Sweadner's watercolor "Amaryllis" isolates a green stalk-supported red flower that's set against a suitably pale green background.Nature's directly agricultural aspect is dealt with in a number of still-life compositions. They include Dana Kleinsteuber's oil painting "Cry For Me," which presents a peeled onion with tear-inducing directness.Charlene Roelecke's oil painting "Three's A Crowd" presents a line-up of three peppers. One is red, the second is yellow, and the third is green. It's colorful proof that there is a pepper for every culinary occasion.Surely the most whimsical still-life subject matter in this exhibit can be found in Candy Aaron's watercolors "Candy Bars" and 'Candy Boxes." The packaging for these bars and boxes comes in such eye-catching colors as red and yellow. What candy-craving consumer could say no to such vivid wrappings for candy brands including Baby Ruth, Good and Plenty and Goobers?It's not often you see candy-themed watercolors in an art gallery exhibit. There are plenty of good-looking artworks in this show, but there's no doubt which ones would taste the best.Brenda Will Kidera and her students exhibit through Dec. 17 at the Bernice Kish Gallery at Slayton House, 10400 Cross Fox Lane in Wilde Lake Village in Columbia.
