Is turquoise04 a chameleon color? Does it change a lot from bag to bag or does it always look more or less the same? Does it tend to have some yellowing with time? What's the difference, in your opinion, with seafoam and vert d'eau? Could those of you who own a turquoise 04 (especially the city) please post pictures? If somebody has turquoise and seafoam, or toghether with vert d'eau in the same picture it would be great for comparison! Thanks everybody!
