B2) Chromatic Syntax - The Art of Retinal Painting
The chromaccord is an improvisational instrument.
"Chromatic syntax" is a group of specific types of color change. Knowing the syntax of color change helps a performer evolve colors by consciously invoking perceptual responses. The results can be dramatic, engaging, exciting, exhilarating, and even mystical.
The basic chromaccord is very simple, like a flute. It has an object and a surround, in this case a cyan circle with a green surround. The performer can change the color of the object, the surround, or both.
In all cases, the speed of color change has a significant influence on the perception of the viewer. The intensity and duration of an afterimage is related to the length of viewing time before the stimulus is removed. The performer can use a range of speeds: slow undulating changes, swift shifts, rapid jumps, or repeated jumps. Flickering has a different effect on the afterimage mechanism.
