# Emotions and Colors in a Design Archiving System: Applying AI Technology for Museums
## 5 Discussion  
The museum archiving system in this study was a retrieval system that grafted emotional data by applying AI technology. In the system, we extracted three main colors from design works using AI technology, matched IRI color schemes using Euclidean distance

We applied the IRI color scheme, which was developed by a survey based on Korean impressions of emotion and color, so it was able to extract emotions with a Korean cultural base. By doing so, it was possible to visualize emotions that were invisible to humans in design works. In addition, this was a new attempt to collect emotional linguistic expressions as metadata from design works through AI technology, which other systems have not tried before. A total of 118 emotional words were used to indicate the ambience of design works based on IRI colors, so it was possible to describe the design works in various ways. To discuss the algorithm used in the system, the validation of matching clustered colors and IRI colors in RGB was shown in the Section 4. The matching algorithm calculated the Euclidean distance to select the closest IRI RGB colors by minimizing the distance between the clustered colors and IRI colors. As a result of the validation between them, it was noticed that IRI colors were well selected, with the highest correlation with the clustered colors. In the system, we conducted an extraction of emotional adjectives from Korean design works that were representative of 2010 to 2012. In addition, through the system, the features of the design works, such as colors and emotions, were automatically archived, and the contents of design works, such as the archiving data, became abundant. The AI system captured the emotional information of design works, converted it into data, and categorized it by assisting in the planning of the exhibition. There are many ways to appreciate and understand design, but this virtual exhibition was planned from a perspective that the archival system, by analyzing emotions through utilizing AI, could also provide a way to appreciate design works with emotion. It was possible to create an effective exhibition by focusing on emotions in design works. This was the pilot usage of the archiving system with a curator organizing a virtual exhibition, and was an attempt to give emotional experience to viewers. When exhibitions are designed to evoke an emotional response in visitors, vision can be harnessed in different ways [16]. In this respect, the archiving system can be used for different curatorial purposes, such as counting colors to create the intended ambience. To conceptualize a space with color, curators can use the archiving system to search design works by colors while considering emotional adjectives tagged by the system. For a curator planning an exhibition while considering spaces divided by specific themes, the archiving system can lead the curator to find suitable design works through categorized colors and emotional data. The limitation of this study was discovering the emotions of the design works only through colors. Colors play the most important role in building a particular ambience, but a way to extract emotions can be found not only through colors, but also through the contents of the design works. The design works contained a combination of elements such as points, lines, and planes, and these became the contents of the works. In this sense, the extraction of authentic emotions can be achieved with the consideration of the contents in analysis. In addition, the emotional and descriptive adjectives in this study were based on scales relevant to Korean culture. Therefore, the results, which were based on the IRI scale, may not generalize across cultures. Thus, the current system may have limited utility to artists and curators from other cultures.
