description of IKB74 by Yves Klein

This fabric-covered panel is six-and-a-half-feet tall, four-and-a-half-feet wide, and is entirely one hue. The color, known as International Klein Blue, or IKB, is a rich, deep blue which relies heavily on synthetic ultramarine pigment. It has an electric, almost neon quality that is unnaturally intense. The potent color covers the entire panel, seemingly uniformly. But on closer inspection there are, perhaps, slight imperfections in the pigment. Horizontal and vertical lines can be perceived, wherein the hue is not quite as rich, and there are some slightly glossy patches down the right hand side of the panel. Or, perhaps, there are not.
