Hi, if you search the older threads someone did a good explanation a while ago - but it's something like this (bad rendition

) - mousse was the first version of this color, and the edging is (I believe) a darker gray/green - gris-vert is the following season, and although the bags are basically the same color leather, the trimming/edging on the gris-vert is more of a purple-y color. Again, this is from memory, so I would do a search, but hope this points in the right direction!
