These enormous sculptural books use zero words and zero pictures– its just page after page after page of colors slowly fading in and out of different gradients. American artist Tauba Auerbach printed the RGB Colorspace Atlas as a record of the full RGB gradient in 3,632 stunning pages of pigmented glory. It’s a digital offset print on paper with airbrushed cloth cover and page edges, bound by Daniel E. Kelm.

The full atlas is a compilation of three books, each of which resembles a solid cube of gradients from afar, as they measure a perfect 8 x 8 x 8 inches. Each volume contains the entire visible spectrum and the spines slice the RBG cube in different directions: vertically, horizontally, and from front to back. Kelm actually does a great job explaining how RGB (something we usually associate with web colors) can be mapped out in print:

Human eyes typically have three types of color receptor on their retinas, each sensitive to a different range of wavelengths of light. The colors associated with these wavelengths are approximately red, green, and blue. Because there are three types of color receptor, it is possible to map the visible spectrum in a three-dimensional spatial model by assigning red, green, and blue each to a dimension.

It is then possible to outline a cube in this space, where the values of red (R), green (G), and blue (B) are visible on a gradient scale of 0 to 100% in their respective directions. These gradients combine to create the RGB color space cube, a volume in which any color can be located by a set of three coordinates.

This is all kinds of amazing– there’s some engineering ingenuity in the bookbinding alone, and the details of spray painted paper edges just really makes this a phenomenal 3D sculptural exploration of color. [Via The Inspiration Grid.]
