Hi Mark,
The car is Blu Lord / Lord Blue - I used to have a standard but for some reason very fast 2000 Coupe' (ALH 555 Y) in the same colour, I remember getting the paint from Brown brothers and theres a rather macabre story attached to the location where the car was painted in Slough.
If it is lord blue code is 438 it would seem to be from 1978 onwards, there are at least two shades of 438 listed one is for autobianchi a112 (on Autocolor chart 438 gm74) and another presumably for lancias (on Autocolor chart 438 fg71) that's just how crazy those Italians are!! The chart I posted earlier is from around 1978 and shows blue lancia, it could be that there was a change over of colour that year the only way to be 100% sure on an individual car is if there is still a colour sticker on the bootlid, year of reg can be confusing as some cars sat around a while, a few years back I had a berlina built in 1979 registered on an x-reg in 1981!! . Later injection cars (that's Series 2 FL2 confusing isn't it!!) were definitely lord blue (but not coupés in UK where AFAIK you could have only red or black unless it was a volumex) ..... oh and I should add that you couldn't get lord blue on any s2FL" coupé in the UK as we didn't get the full colour range
