Membrane colors of inferior nasal turbinate and lower lip vermilion were measured by newly designed photoelectric colorimeter connected with selfoc needle scope as a senser.Measurement was performed by way of Tristimulus Value Method under JIS-Z-8722 based on modern science of color. The subjects were 61 adults with ages from 19 to 45.Chromaticity diagram was figured from tristimulus values of the subject color. Compared with the chromaticity diagram and the systematic color name recommended by international society of color council, it was found that membrane color of nasal turbinate belongs to yellowish or orange pink zone, color of lip belongs to pink or reddish pink zone. According to result from another measurement with Fast spectrophotometric colorimeter, absorption bandsaround 540nm to 576nm were found on specter of nasal turbinate and lip vermilion. Also forehead skin color showed similar spectral pattern. Since these absorption bands on wave length of the color well coincide with that of oxy-hemoglobin in blood stream, hemoglobin pigment always have large influence upon the membrane color or skin in human body. Measurement under ischemic condition with pressure upon the membrane and skin was also performed.A bibliographical review of photoelectric colorimetry since 1978 was also included.
