To structure time with abstract visual materials requires a visual grammar of line, shape and color. Color is especially problematic, difficult to measure in all but the simplest applications; the literature of color theory and harmony is often confusing. To devise a syntax for structuring time with color, one can turn to the concepts of tension-release, of neutral, balanced and weighted color domains and of discrete computer raster images; they help to create and measure time-based color compositions.
