Chromaticities
2.1.1 The chromaticities of aeronautical ground lights shall be within the following boundaries:
CIE Equations (see Figure A1-1):
a) Red
Purple boundary | y = 0.980 – x
Yellow boundary | y = 0.335
b) Yellow
Red boundary | y = 0.382
White boundary | y = 0.790 – 0.667x
Green boundary | y = x – 0.120
c) Green
Yellow boundary | x = 0.360 – 0.080y
White boundary | x = 0.650y
Blue boundary | y = 0.390 – 0.171x
d) Blue
Green boundary | y = 0.805x + 0.065
White boundary | y = 0.400 – x
Purple boundary | x = 0.600y + 0.133
e) White
Yellow boundary | x = 0.500
Blue boundary | x = 0.285
Green boundary | y = 0.440 and
y = 0.150 + 0.640x
Purple boundary | y = 0.050 + 0.750x and
y = 0.382
f) Variable white
Yellow boundary | x = 0.255 + 0.750y and
x = 1.185 – 1.500 y
Blue boundary | x = 0.285
Green boundary | y = 0.440 and
y = 0.150 + 0.640x
Purple boundary | y = 0.050 + 0.750x and
y = 0.382
Note – Guidance on chromaticity changes resulting from the effect of temperature on filtering elements is given in the Aerodrome Design Manual, Part 4.
2.1.2 Where dimming is not required, or where observers with defective color vision must be able to determine the color of the light, green signals shall be within the following boundaries:
Yellow boundary | y = 0.726 – 0.726x
White boundary | x = 0.650y
Blue boundary | y = 0.390 – 0.171x
2.1.3 Where increased certainty of recognition is more important than maximum visual range, green signals shall be within the following boundaries:
Yellow boundary | y = 0.726 – 0.726x
White boundary | x = 0.625y – 0.041
Blue boundary | y = 0.390 – 0.171x
