I am pretty sure my brother's turned white which is why I doubted it. The seller has a greyer one, so I might grab them both, but I think the other one is more of a really dark blue.
I really wanted a grey coloured silkie after losing mine a few months ago.
I got offered this one and have arranged to pick it up, but after looking at other photos here, I am now wondering if it will be grey or is actually a white.
