초록

본 연구는 도심지의 산책로나 보도블록에 가장 적합한 황토색을 구현하기 위해 실제 산책로의 황토를 채취하여 측색실험을 진행하였다. 또한 사용자 선호도 조사를 통하여 보도에 사용되는 시멘트복합체의 적절한 황토색 표준을 제시하고자 하였다. 부산지역 산책로 3곳에 대한 색도(chromaticity)는 $a^*$ 값(value)이 3.6~13.6, $b^*$ 값이 11.4~23.4의 범위로 나타났고, 명도(lightness) $L^*$ 값은 3개 지역이 거의 비슷하게 나타났다. 사용자에게 익숙한 황토색 시멘트 복합체의 색의 표준을 정하기 위해 선호도 조사를 진행한 결과 $+a^*$의 값인 적색계열과 $+b^*$의 값인 황색 계열이 높은 적색과 황색계통이 많이 엿보이는 색을 선호하는 것으로 나타났다. 실험결과와 선호도 조사를 분석한 결과에 따르면 보도에 사용되는 시멘트 복합체의 황토색은 $L^*$ 32.2~45.8, $a^*$ 5.2~13.6 $b^*$ 15.8~21.2의 범위가 적정한 것으로 나타났다.

This work aims to suggest the most proper Hwangtoh color(ocher) for sidewalks and walkways located at the central part of the city. The actual colors of Hwangtoh samples that were obtained from 3 different locations (mountain walkways) in Busan were measured. In addition, personal preferences of such Hwangtoh colors were evaluated through survey in order to provide a proper standard reference color for urban walkways and sidewalks. With respect to the chromaticity of Hwangtoh obtained in Busan, $a^*$ and $b^*$ values were found to range from 3.6 to 13.6 and 11.4 to 23.4, respectively. It was also found that $L^*$ (lightness) values of 3 different Hwangtoh samples were found to be similar. According to the results from survey, higher values of $+a^*$ (red type) and $+b^*$ (yellow type) were preferred, indicating the red and yellow color needs to be developed stronger from Hwangtoh. Based on these findings, the proper Hwangtoh color used for walkways in urban area was chosen. It was found to be $L^*$ for 32.2~45.8, $a^*$ for 5.2~13.6, and $b^*$ for 15.8~21.2, respectively.
