Abstract
If the human skin is observed through a polyester or silk plainweave habutai or crepe de chine, the variation may be observed in the chroma of the color of the human skin. A goniophotometric colorimeter was used to measure the variation of the skin color which might be affected by the incidence and the receiving angle of fabrics. The following results were observed:
(1) The distance between a fabric and the skin has little effect on the color variation.
(2) From a specular reflected direction at a raceiving angle of 45°, it is difficult to perceive the skin color. With the receiving angle between 0° to 30° the color of the fabric and skin color form a twocolor mixture resulting in the easy perception of the human skin color.
(3) The skin color is less perceptible through a crep de chine, compared with a plainweave habutai, due to rough fabric surface.
(4) The skin color is less perceptible through a silk plainweave habutai, compared with a polyester one, due to the better light diffusion quality of the silk fiber.
(5) The human eyes can perceive the human skin color at a wider receiving angle than a goniophotometer can do.
