Detection of Color Information Using Color Diagram

In the majority of food research studies, sample colors are presented as CIE L * a * b* values. However, it is difficult to estimate the original colors of food samples directly using L * a * b * values. In this study, color images were obtained using a conversion program (Adobe color web tool) to check colors derived using a colorimeter. In addition, the suitability of a cell phone camera as a food color measurement tool was investigated by comparing its results with those obtained using a colorimeter. An initial examination showed that the L * a * b * values of five random colors measured using the colorimeter and cell phone corresponded well with original colors. However, the L * a * b * values of kimchi stems, kimchi soup, banana, and makgeolli obtained using the cell phone were higher than those obtained using the colorimeter, and surprisingly, the cell phone was found to reflect the original colors of 20 food samples better than the colorimeter. Although color measurements obtained using a cell phone camera are not suitable for precise measurements, a cell phone camera might be useful when professional colorimetry equipment is unavailable. This study is meaningful because it suggests a new method for directly presenting color images.
