This study is about the general education of synthetic dyes provided during the Japanese colonial era. Synthetic dyes were distributed in South Korea since they had been imported from the West in the late 1880s. In the early stage, synthetic dyes produced in western countries through the intermediary trade between Japan and China. Then, in the 1930s, when Japan’s synthetic dye industry began in earnest, Campaigns to wear Color Garments(色服奬勵運動) was developing, led by institutions. There was a difference according to the region, but in fact, people were forced to wear colored clothes. Dyeing and weaving factories(染織工場) produced dyeing fabric, and linen shops sold dyeing fabric, but generally, dyeing took place at home. There were some dye houses(染色所) operated by experts who had been trained in a professional educational institution, but it was difficult to use them in farming villages since they were expensive and rare. As the synthetic dyes were expensive, farmers(農民) were reluctant to purchase them, so some institutions first provided the synthetic dyes for low-income classes, receiving support from local notables. Dyeing at home was done mainly by housewives. Housewives who were busy with housework learned the theory of synthetic dyes and the dyeing method through newspapers, radio, and a short dyeing course. This study investigated how the synthetic dye education was conducted for general citizens during the Japanese colonial era. The research method is literature research. This study analyzed the subjects and courses recorded in the printed media(印刷媒體) such as newspaper articles, magazines, and advertisements published during the Japanese colonial era.
