Raman spectroscopy is the powerful spectroscopic tool that non-destructive in investigation of chemical compounds of materials. The Raman spectroscopy as a non-destructive methodology is demonstrated of published literatures [1]. It has not only non-destructive analysis but also a variety of advantages. It measures molecular vibration mode from scattering light according to lasers. Therefore it detects to the chemical composition, bonding, and structure of the sample material [2]. Furthermore, the Raman spectroscopy has benefit such as in situ monitoring and portability. These characteristics provide sensitive measurement to analysis at art and cultural properties because of the Raman spectroscopy do not damage at sample that have substantially historic worth and also provide a chemically fingerprint about the identification of materials. However, pigments had variable colors interrupt to measure Raman signal because of its radiating fluorescence. Therefore, we study identification of traditional Korean pigments using variable lasers. These are important to avoid fluorescence and take enhanced Raman signal from the resonance Raman scattering (RSR) effect that increases scattering efficiency because of that is related region of electronic state [3]. Resonance Raman measurement was performed a microscope (Olympus Bx73) that coupled to a spectrometer (Andor Shamrock 303i) with charge coupled devices (Andor iDus 420) using by 488 nm Ar-ion, 532 nm diode, and 632.8 nm He-Ne lasers. The pigment is used lumber painted Korean traditional pigment such as painted Sungnyemun Gate. In conclusion, we study using the resonance Raman methodology for analysis of pigments that have color be of help chemical identification and make database. It be of help for preservation and restoration Korean cultural properties. 1. G. Burrafato, M. Calabrese, A. Cosentino, A. M. Gueli, S. O. Troja, and A.
