Zooker, very true. And - in the US particularly - the use of only blue sideline taxiway lights, and only rare use of green centreline lights, is awful. You're faced with a sea of blue - blackness - blue - blackness - blue.... Some of the blackness is taxiway but most is not. But try distinguishing which bit of blackness is the taxi bit & which is not at a strange airport bloody difficult.
Centerline greens, however, are a much better way of marking the way. You have a clear line of breadcrumbs to follow.
