I actually got a peek at the new colors today!!!
I couldn't very well pull out my Ulysse and write down everything
but I did manage to make a couple of discreet notes.
What I learned: my overall impressions of the new color palette was that almost all the colors are very muted, with the exception of two different *very bright* turquoise colors, and a new and absolutely stunning red.
The new leathers as far as I could tell were:
1) a new type of Clemence with a much heavier, larger grain, and much thicker overall.
2) a new calfskin called Veau Tadelakt, that is heavy and smooth, but not as shiny as box. It seemed a bit more scratch-resistant as well.
3) As mentioned previously, Chevre Mangalore, which is a finely grained goatskin. I was unable to determine whether it will replace CDC or...?? Mangalore is much less grainy and even lighter weight than CDC. The sample I saw was in Vert Olive, which was absolutely stunning.
4) Veau Sikkim: Very smooth and light, quite similar to Swift, but again it seemed a bit more scratch-resistant.
As for colors, the main one that I fel in love with was Rouge Piment, the new red I mentioned. It's a blue-toned deep red, almost a cross between Rouge H and Rouge Garance. However, according to my contact, this leather will not be offered for bags, only for small goods like agendas. There was also a new taupe-y color, lighter and less cool in tone than Etoupe, but I didn't get the name of it (it was the one that was in Mangalore in the book I saw). The other colors included Curry (just what it sounds like), a new brick-ish color, another mustardy color with a lot of green in it, and similarly muted tones. There was also a really beautiful warm brown, called Marron something (not Marron Fonce); the sample I saw of this was also very heavily grained.
Hope this is helpful!!
