Green Painted Taxiway Centerlines?

Hi, I came across this picture in Nuremberg which shows green painted taxiway centerlines.

I had seen green centerline lights used at night, which are also visible on this picture along the paralell taxiway behind the aircraft, but I had never seen green painted taxiway centerlines. Does green paint have any special meaning? The taxiway centerline that is being followed by the aircraft is regular yellow. There's a definite distinction among the two, and it would be more noticeable during daytime. Any insights?

I'm not entirely sure but i think it is something that aids visibility on the ground in snowy conditions, similar in Switzerland they have yellow markings on the runways at certain airport to aid better visibility on the ground with snow etc. Or perhaps they may have just run out of the yellow marking  Wink .

Maybe something to do with the fact that when there are aircraft parked there (as there are in the photo), you can't actually use that taxiway?

Just a guess.

I thought that ICAO did away with the color coded routes. Not sure the reason. At IAH we use "Spots" (big round yellow spots with a black number emblazed in the middle) to mark entrance and exit corridors into the ramp control area. (When we re-did out last spot last month, I know there was something about that was the ICAO preferred or mandated way...not 100% sure).

I think FRA has colored centerlines on a portion of the ramp as well - just from memory, the center one is yellow, and is used for big planes, but there are two other centerlines on each side which can be used for smaller planes with smaller wingspans.

This reminded me of the following related thread referring to yellow runway markings in Norway.
RE: Yellow Runway Markings- Why? (by JHSfan Aug 18 2006 in Civil Aviation)

I can't recall seeing yellow runway markings in Switzerland, at least at the major airports (GVA/ZRH) but perhaps you are referring to smaller airports.

Just to name a few examples of airports with yellow runway markings, some of them are SVG, KSU and OSL.

The way it looks, Norway is probably the only country (or one of the very few countries) with these yellow markings, probably due to its close location to the polar circle.

Japan also has at least one runway marked with yellow.

Last I saw Niigata it was marked in yellow.

I believe that Yamagata is also yellow, but have never been there... Sounds like it's time to sechedule another vacation.

Yes, on the ramp in front of terminal 2, between the E/D positions at the terminal and the V positions on the far side of the ramp. The line running along the center of the ramp is yellow (for big planes), but there are two additional lines, one blue, the other orange, for aircraft with a smallr wingspan, which then fit on the taxiway side by side.

Why would proximity to the polar circle be a factor causing one to paint runway markings yellow instead of white?

MUC has similar coding for T1 too, and for some of the T2 "crossovers"

T2: See the lower left. The "main" taxiways are apparently widely spaced  Smile

T1: Best to see in the middle between the UA and US tails, a red and a blue curved taxiway.

I think RYN has blue taxiway markings adjacent to the standard yellow, to guide pilots to the transient parking and restaurant - hence it is known by some as the 'blueberry pancake' line!
