Part A: The Chromaccord (Home)
A chromaccord is a visual display instrument that allows adjacent areas of color to be changed. The purpose of the instrument is to project colors on the viewer's retina and induce neural responses. The screen design is a retinal homologue; the circular object stimulating the cone-rich area near the fovea, and the surround colors spread over the rest of the retina.
Multiple colored lights behind a diffusing screen are controlled with dimmers on a console. The color areas are separated with barriers behind the screen. With an instrument like this, exploration of the visual response to kinetic color becomes spontaneous.
This instrument, built in 1999, uses 212 small bulbs with a color filter on every one. The color of each area is controlled by six dimmers, three primaries and three secondaries that can be faded on or off to illuminate the screen with any of the colors and any of their additive combinations.
The intended method of viewing the chromaccord is for the viewer to lock the circular object to the central portion of the retina and let the surround act on the periphery.
