My ceramics prof preached "truth in materials." Clay should look like clay. But he was pretty amused when I painted the pieces that I couldn't get into the glaze firing. "Ah, room-temperature glazes," he said. But truth in materials stuck with me. Candy colors are a lot of fun over opaque bases. Wood should look like wood. Still, candies over curly maple looks gorgeous. Most pretty wood should be left alone, but every now and then an all-over sunburst will take your breath away, even on koa. Loosen up, guys. But you're also right, its not easy to do.
