I vote for Violet. Bear this in mind though, if this is a bag that you will be using quite a lot, go with the Violet, if this is a bag that you will use when the urge strikes you, then go with the Vert D'eau. I think that in the long run, Violet is going to wear far better than the V D'eau. There have been posts about the V D'eau fading and yellowing with time, not so with the Violet.
I wish you well,
Bridget
