This study investigated the influence of color psychology-applied group art therapy on the ego-identity and emotional intelligence of university students. Both the experimental and control groups consisted of seven volunteers from universities in Seoul, and a total of 14 sessions were performed for the experimental group(80 minutes / session). Korean type ego-identity test and adult emotional intelligence tests were used as research tools. The Wilcoxon signed-rank test was used for the SPSS 21.0 statistics program to verify the pre- and post-effectiveness of the therapy. The KHTP figure test was also performed, before and after the group art therapy, to analyze the changes seen through the course of this study. The results are summarized as follows; First, the group art therapy using color psychology showed a statically positive effect on the university students’ ego-enhancement. Second, the therapy improved their emotional recognition and emotional regulation, which are the subareas of the emotional intelligence. Third, they discovered their own interests and benefits for themselves and constructed specific career plans for a positive future self. In the intermediate steps, particularly, they understood the symbols and the images of colors and explored themselves through a representation of color psychology containing their own emotions and feelings. They appeared to have an opportunity for self-introspection.
