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 Recommendation.— Where dimming is not required, or where observers with defective colour vision must be able to determine the colour of the light, green signals should 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 Recommendation.— Where increased certainty of recognition is more important than maximum visual range, green signals should 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 * See CIE Publication No. 15, Colorimetry (1971). 2007/70/II. szám Annex 14 — Aerodromes Volume I 25/11/04 APP 1-2 2.2 Discrimination between lights 2.2.1 Recommendation.— If there is a requirement to discriminate yellow and white from each other, they should be displayed in close proximity of time or space as, for example, by being flashed successively from the same beacon. 2.2.2 Recommendation.— If there is a requirement to discriminate yellow from green and/or white, as for example on exit taxiway centre line lights, the y coordinates of the yellow light should not exceed a value of 0.40. Note.— The limits of white have been based on the assumption that they will be used in situations in which the characteristics (colour temperature) of the light source will be substantially constant. 2.2.3 Recommendation.— The colour variable white is intended to be used only for lights that are to be varied in intensity, e.g. to avoid dazzling. If this colour is to be discriminated from yellow, the lights should be so designed and operated that:
