Could someone look at the 2 green B'bags on the Bob Ellis site and tell me which one is Emerald--the lighter one or the darker one? Or are they both Emerald under different light? I'm very confused about this because there's also 2 greens in Barneys and it seems like Emerald would be the lighter one, but then--what's the darker one? I can't find another color swatch that makes any sense at atelier.naff either. Thank you.
