Alignment and amplification as determinants of expressive color

摘要

Abstract: Color alignment and amplification are explored within the context of a windowed system in a computer workstation. Color alignment allows precise specification of color relatedness while, at the same time, accounting for interaction of surrounding visual field and state of visual adaptation. Alignments represent the basic unit of color experience, and are formed by any two hues in color space. An experiment which utilizes the color alignment model developed by Jacobson and Bender is presented. The experiment measures preference for type of alignment between text color, background color, and highlight color, in a workstation. Results of this experiment provide guidelines for effective selection of colors for window, font, and highlight for any given application within the windowed system. Of particular interest is the incorporation of color alignments into the window manager, so that local colors can be coordinated with global colors to provide a variety of expressive signals.!
