1. Introduction

Gimhae-si is ancient capital of Geumgwan ‘Gaya’ (the 5~6th century). As if proving the fact, lots of relics were excavated and the city has historic identity. Various colors have been applied to public facilities, etc. under the name of 'colors of Gaya' during the policy process of Gimhae-si, but they have been just used subjectively and confusion has been caused for applying them with more objective standard of colors. The purposes of this research are to establish historic regional identity of Gimhae-si firmly and develop color guideline of Gimhae-si so as to prevent confusion for using colors of Gaya.

2, Research Methods

For the method of this research, functions and roles of colors, regional identity and environmental colors were theoretically considered and method to establish region's representative colors, essential conditions, etc. were analyzed by analyzing color guideline of other regions. Thus, this researcher intends to examine what color guideline of Gimhae-si must seek and differentiate. In addition, objective and systematic guideline is established by investigating the process to establish Gimhae's representative colors and color guideline.

Ⅰ. Representative colors are selected by applying spectrocolorimetric equipment to Gaya relics excavated in Gimhae-si. But, relics which cannot be directly colorimetric are applied by web-color analysis method.

Ⅱ. By selecting colors which represent each relic, range of color, brightness and chroma is suggested and color guideline for each relic is established by suggesting dominant color and secondary color.

Ⅲ. Color guideline suggested is applied to public facilities and public building and applications are suggested.

3. Result

According to the general plan of urban design of regional community, harmonized design reflected by each characteristic is suggested as preemptive practical strategy through the analysis on cultural, natural, social and historic characteristics of the region. With the minutely colorimetric method of Gaya historic relics excavated in the region, total 36 symbolic colors of 6 groups were drawn. And, rationality and identity of this research can be found as it defines symbolic colors of the region by depending on more realistic grounds.
