Paldalmun gate was built in 1794 as the southern gate of Suwon Hwaseong. The signboard's paintworks of Paldalmun gate was applied to the signboard of the state-run building in the 18th century. The signboard of Paldalmun gate was repainted along with the building when repaired in 1969. In that time, the signboard's paintworks during the reign of Jeongjo era was transformed. The purpose of this study is to restore the image of Jeongjo era paintworks on the Paldalmun's signboard, which has been modified since the 1960s due to modification. For the purpose of the examination, we examined the traces of paintworks remaining on the signboard of Paldalmun gate and examined several state-run signboards decorated with 'Yukhwamoon' paintings similar as the signboard of Paldalmun gate, which made around the 18th century. Through the above-mentioned researches, typical color features were identified in the decorated with 'Yukhwamoon' paintings on signboard in the 18th and 19th centuries. In addition, the type of pigment used in the signboard's paintwork of Paldalmun gate was verified through the 『Hwaseong Seongyeok Uigwe(華城城役儀軌)』 and the 『Han-gul Jeongri Uigwe(한글整理儀軌)』, while analyzing the characteristics of age-related deterioration according to the type of paintworks in various traces of pigment coatings remaining on the signboard of Paldalmun gate.

Copper trihydroxychloride (atacamite, botallackite, paratacamite, etc.), the first green pigment used in Mogao Grotto's mural paintings of China, has been known as "copper green", "green salt", and "salt green", etc. and has been used as an important green pigment with malachite. At first, the natural mineral atacamite was employed, but after the Five Dynasties (907~960 CE), synthetic copper trihydroxychloride was primarily used. In Chinese literature, copper green, green salt, and salt green are recorded as being made via reaction with copper powder, Gwangmyeongyeom (natural sodium chloride), and Yosa (natural ammonium chloride), and the prepared material was analyzed to be copper trihydroxychloride. Copper trihydroxychloride pigment was not found in paintings prior to the Joseon Dynasty (1392~1910 CE) in Korea. In analysis of the green pigments used in paintings and the architectural paintworks in the Joseon Dynasty, copper trihydroxychloride was also shown to have been used as an important green pigment with malachite (Seokrok). In particular, the proportion of copper trihydroxychloride use was high in Buddhist paintings, shamanic paintings, and dancheongs (decorative coloring on wooden buildings). Some of these turned out to be synthetic copper trihydroxychloride, but it is unclear whether the rest of them are synthetic or natural pigments due to a lack of analyzed data. From literature and painting analyses, the pigment name of copper trihydroxychloride in the Joseon Dynasty turns out to be Hayeob, a dark green pigment. It is believed to have first been prepared by learning from China in the early Joseon period (early 15^th century) and its use continued until the late 19^th century with imported Chinese pigment. Round or oval particles with a dark core of copper trihydroxychloride which were used in Chinese literature were similar to the synthetic copper trihydroxychloride pigments used in the Joseon Dynasty and Chinese paintings. Therefore, the synthetic copper trihydroxychloride pigments of Korea and China are believed to have been prepared in a similar way.
