thank you all for your information - it is much appreciated.
Emmi, thanks for taking the time to look again and provide more info as well.
The pic you showed looks a dark grey/green to me on my monitor- is twilight a dark grey/green? I would say my photos make mine look a lot more brown than it is in reality apart from down the sides of the full pic vase which look quite good - that's having looked again in daylight (sorry just had to get to work today finally

so no time to take pics in daylight). But that said ...it is definitely still a green with a brown hint, not a green with a dark grey hint if ykwim? Other than that I think it looks the same as the catalogue pics and the other link pics when seen in real life.
I only have 4 pieces of w/f two of which I'm not keen on (ribbon trails, sapphire and sea green) and one ruby knobbly, so I have nothing to compare to.
I hope it is W/f, that would be very pleasing
