The purpose of this study is to propose an achromatic color that excels in readability and fatigue degree and helps improve short-term memory in order to implement a suitable environment for mobile users to receive information in Hangul(Korean alphabet) quickly and efficiently. A total of 59 smart phone users who use Hangul were tested for readability and fatigue degree in five achromatic colors, Bk, N2, N4, N6 and N8, and for short-term memory in the same achromatic colors. For legibility and fatigue degree, readability and fatigue degree were measured by quantifying each achromatic color word using the Likert scale, and short-term memory analyzed the number of memorization words by color. The words used in the short-term memory experiment were all two syllables, and were extracted from the Korean language textbook of the second grade of elementary school. In the case of readability, N2 was assessed to be more legible than the darkest Bk of the five stimuli, after which readability was reduced as photometric values increased. In the case of fatigue degree, it was also found to be the most comfortable at N2, which was slightly lightness higher than the completely dark Bk, and later felt uncomfortable as the lightness increased. The results of short-term memory experiments showed that the number of words memorized increases as lightness value increases, and then drops sharply from N8, the brightest of the five stimuli. The achromatic color best suited to improve short-term memory was the second lightest N6. The results of this study show that N6 was better in short-term memory, but which was a little disturbing to read. Through this study, we hope to use appropriate colors to provide a better environment for users, depending on the type of information in the mobile environment.
