不同色彩背景會影響色塊對人眼視覺的刺激，使得相同色塊三刺激值卻有所改變。本研究希望了解不同彩色背景對於不同亮度之灰階色塊與不同面積大小之灰階色塊所產生之誘導特性，而設計了一套實驗。實驗中採取六種不同的彩色背景、三種亮度的灰階色塊、三種不同面積大小的灰階色塊，共設計出五十四種組合，製作操作介面進行測試後，進行心理物理實驗，取得每個組合新的三刺激值。得到新的三刺激值便能將資料繪製在CIE u'v'色度圖上，進行結果分析與探討。
Different color backgrounds will make the same color patch change its color appearances. This study intends to understand how background colors and patch sizes affect the visual appearances of neutral color stimulus according to the performances of the several psychophysical experiments. The test color targets include 6 background colors, 3 luminance levels of central neutral colors and 3 central neutral colors. Totally 54 kinds of test combinations are designed in the psychophysical experiments. The software system of Visual Studio 2005 is used to product test interface platform. The experimental results will be plotted at CIE u'v' chromaticity diagram to analyze the color induction effects of patch sizes and background colors.
