This paper constitutes a second report regarding an experiment examining the relationship between color recognition and concomitant color expressions as experienced by middle school students and high school students. The experiment’s protocol required three steps: first, sixty subjects viewed 308 color chips; next, they recorded by themselves the proper color terms for those color chips; last, they selected the proper color terms matching both color chips and color terms. This experiment yielded several notable discoveries related to color recognition and concomitant color expressions. First, in the task examining systemic color terms, only 22.72% answers corresponded with the systemic color terms of KS A 0011. Especially notable was that the ‘Yellow’ color terms (31.35%) were at the top of the correspondence degree and the ‘Red’ color terms (16.58%) were at the bottom degree. Second, the task relating to idiomatic color terms revealed that ‘Namsack (dark blue), Bora (deep purple), Jaju (deep purplish red)’ color terms (23.33%) were at the top level and ‘Red’ color terms were at the bottom. Next, we elucidated three controversial points regarding KS A 0011: Lee, Hyun-hee․Shin, Ho-cheol. 2012.
