Thanks for replies gentlemen. Looks like it's the tail that has to clear the color-coded line. I would still appreciate some official refernence (Icao annex or some such)...
The reason I am asking all this is not to "submit report at the exact moment in time if I happen to care" as Hahn suggested. It's because the other day, in an effort to clear the tail from the ILS sensitive area I taxied beyond clearance limit, which happened to be at the end of the color-coded line (and was inadequately lit, or at least I couldn't see it). I just want to avoid similar misunderstandings in the future...
