RGB Colorspace Atlas, 2011

"In my view, the defining feature of digital language is that it quantifies whatever is put into it and makes it granular. Ambiguity and fluidity are represented by strategically arranging unambiguous and discrete units. When quantifying color digitally, people had to ask what a suitable unit size would be, and as i understand it, in the standard digital RGB space, there are 256 possible values of each primary, so you get more than 16 million discrete colors.
I personally I love the RGB cube because of it’s elegance and relationship to the way we perceive space. Each of the three light primaries— red, green and blue— is assigned an axis , and the cube is essentially defined as the area within which the values for red, green and blue go from 0% - 100%. At the origin, where all three values are zero, there is no light and so that corner of the cube is black. At the opposite corner where all three values are a 100%, there is all light and so that corner is white. The other six corners of the cube are the light primaries and light secondaries, which also correspond to the process primaries - cyan, magenta and yellow.”
