Abstract: The colored luminous fiber is a new kind of functional textile material, which gives off emissive color light in darkness. Under colored pigment and luminescence material influence, there is a certain deviation in the color and emissive color of luminous fiber, which affects human visual perception and feelings given by colored luminous fiber. By testing color performance and emissive light color performance, this paper discusses the relationship between the color and emissive light color. The results showed that the color properties of colored luminous fiber showed in lighting are similar to that of ordinary fiber. The hues are great differences between the colors. The absorption of light is enhanced with the increased K/S value, which results in deeper color. In darkness, emissive light color of colored luminous fiber is mixed with yellow light and green light. There was no obvious difference among the hues of emissive light color, but luminous intensities are different.
