Title Safety color perception under HID lighting.
Bibliographic information 16 Sep. 1976, Vol.30, No.19, p.128-130. Illus. 3 ref.
Abstract This study attempted to discover (1) if any safety colour (red, orange, yellow, green, blue, purple) could not be identified under mercury, metal halide or high-pressure sodium lighting and (2) if these light sources are sufficient for discrimination of the colours. Plant conditions were reproduced for discrimination of the colours. Excellent mean identification was realised for all colours except orange under mercury lighting. The mean of observers correctly identifying the colours under incandescent, various types of mercury arc, metal halide, and high-pressure sodium lighting at 10 foot-candles was 99%; at 5 foot-candles it was 97.8%.
