| Summary: | 碩士 === 國立臺灣大學 === 園藝暨景觀學系 === 102 === Landscapes are composed of various elements and colors. Colors play an important role and are never seen in isolation in our daily lives; however, there are few color studies on environmental space. With the recent trends of environmental protection and urban renewal, an effort is made herein to make a region reveal its own ‘personality’ regardless of the artificial facilities in a natural landscape. Studies have shown that color attributes strongly affect emotions and preferences; emotions and preferences were not only influenced by landscape elements and space sequences, but also have a strong relationship with color harmony. The main part of the study is aimed at finding the relationships among colors, emotions and preferences. This study is separated into two experiments. First, we collected 200 photos and used the software Image J to convert the RGB color space of the photos into CIEL*a*b* color space; we then evaluated color harmony and landscape preference through questionnaires. According to the result of color harmony evaluation from experiment 1, we chose 60 photos for the stimulus of experiment 2 and conducted a survey with 3 variables: emotional experience, color harmony and landscape preference. The emotional experience variables consisted of 8 different scales: tense, relaxed, afraid, calm, excited, bored, pleased and gloomy. We then tried to see if the CIEL*a*b* color space model reflects the Emotional Experience model. The results showed that there were differences among color attribute, color harmony, emotional experience and landscape preference. Color harmony had strong correlations with emotional experience and landscape preference. Under the stimulation of a natural landscape, when one feels harmonious, one will have a stronger relationship with positive emotions; the more positive the emotions, the higher the preference. This finding verifies the concept of emotion as a mediator between environment and behavior responses. Additionally, the CIEL*a*b* color space can be matched with the environmental psychology model. Through the results, we can determine the relationships among color attribute, color harmony, emotional experience and landscape preference. With the importance of color harmony to the natural environment, the study results can provide the basis for future planning and design reference.
