The emphasis of the color impression of planar cotton broad fabrics with 6 individual colors, RED, YELLOW, GREEN, BLUE, WHITE and BLACK, has been evaluated for spot lightings, compared with base lightings, by sensory evaluation method with 13 adjectives. The spot lightings used were 4 combinations of the LED lamp of neutral white color or electric lamp color with the base lightings of the fluorescent or incandescent lamp. On the basis of the preceding work on the examination of color impression emphasis by the base lightings with fluorescent lamp or incandescent, the present examination of the color impression emphasis by spot lightings resulted in the following 6 conclusions: (1) the 13 adjectives are divided into two groups, the 6 adjectives, “light”, “Clear”, “Showy”, “gay”, “brilliant” and “glossy” with great number of emphasis, and others with much less emphasis; (2) the low illuminance, such as in Pret-à-Porter shop, the impression emphasis was observed for rather many adjectives independently of the above grouping; (3) the tendency of the emphasis under the base lightings was succeeded to that under the spot lightings, as the impression of RED or BLUE emphasized under the incandescent lamp or fluorescent was emphasized under the spot lighting with the electric lamp color LED lamp or with the neutral white color LED lamp, respectively; (4) through the 6 adjectives, the spot lighting of the neutral white color LED lamp added on the incandescent lamp was selected for the most general impression emphasis to be realized; (5) the former selection of the spot lighting resulted in remarkable reduction of the number of case with the depression effect by the spot lightings for the color impression, compared with the base lightings; (6) an example of the direction suggesting the selection of the lightings effective for the emphasis of the objective color impressions has been proposed.
