The purpose of this study was to contribute to the utilization of color in psychological diagnosis by analyzing the relationship between color preferences and psychological tendency. In particular, we paid attention to whether the psychology of preferring yellow is related to “thinking”. The subjects of the study were 306 university students (male: 59, female: 247) in Gangwon Province and Jeollabuk-do. The measurement instruments were 13 colors, and the Semantic Differential Scale was used to scale for seven items on both sides. The processing of collected data was conducted via frequency analysis of color preferences and factorial analysis for the seven items on both sides by using the SPSS 24 program. In addition, one-way ANOVA was applied to four groups (Thinking, Feeling, Intuition, Sensing) classified by factor analysis in order to determine the difference of psychological tendency in color preference, including for yellow, among groups. The LSD test was performed by post test. The results of this study are as follows. First, the preference for yellow was related to “feeling” rather than “thinking”, and the “the thinking” was highly related to a red preference. Second, especially, in the preference of green-yellow color, the “intuition” is high and the “sensing” was low, and the preference for yellow-red was high on the “sensing” and low on the “intuitions”.
