Description
Summary:碩士 === 國立成功大學 === 工業設計學系 === 86 === Hue assimilation and simultaneous hue contrast, each of the characters areopposite, change the color attributes of hue pair. We define these colorperceptions, which are the result of juxtaposing two hues, as " the per-ceptions of hue pair ". The phenomenon results to the color attributes ofhue pair itself. This research explores the result of juxtaposing two hues to be hue assimi-lation or simultaneous hue contrast, the degree of hue shift, and the sen-sory threshold which in certain visual angle or ratio of color area when huepair changes its color perception. The visual angle is determined by one strip in hue pair. Color samples was displayed by color computer monitor.We adopt HLS computercolor display system to resolve the limit of matching Munsell color papersand to response the trend of computerize. HLS values, the results of thisresearch, will be converted to RGB values and CIELUV values by converse formulae( HLS-RGB-CIEXYZ-CIELUV). And then, we measured hue shift result fromhue pair by CIELUV-1976 hue difference formulae. We adopt the method oflimits and the method of constant stimuli in procedure to quantify the sen-sory threshold of transition between hue assimilation and contrast and thedegree of hue assimilation and simultaneous hue contrast under differentvisual angles and ratios of color areas. The result demonstrated that the hue shift of hue pair is approximately inverse related to the hue difference, cubic related to the visual angle,and linear related to the log value of ratio of color area. With the end ofthe research, designers will be able to easily process color planning and color assorting under various visual angles, ratio of color areas, and to upgrade the quality of color use.
