Abstract
The aim of this research is to obtain systematical basic data for the designs and colours of clothing.
The women tested by us were students of some girl's junior colleges in the Sapporo area, at the age of nineteen, totaling 72 persons.
Each test was held by the visual method of measurement. One test was held in winter January 1970 under the condition of room temperature approximately 6°C with humidity of about 40%, and the other test was held in summer early July 1970 under the condition of room temperature approximately 23°C with humidity of about 60%. Light given on the skin surface was 450 to 500 lux.
As a result, girls with a high grade of lightness 7.5 YR were seen noticeably, but many of them were found to have the shade 10.0 YR in winter, while in summer more girls. had the same shade 10.0 YR but of less tints. This result was so high that we could not find in the results of other areas.
