bought some paint a while ago just to touch up some areas and i asked for gulf blue L390, i got home, prepped everything, set up compressor, opened paint and it was blatantly green

at first i blamed the paint shop but then i checked on thesamba.com's resources and for gulf blue L390 both colours come up under the same code, even when i find pictures of other bugs painted in gulf blue some are green and some are the same as mine. could anyone shine some light on the matter ?

i luckily had some paint the last owner had for the car but it was just enough for the touch ups and its a perfect match but i'd like some more.....
