It has come up distinctly blue-ish in the photos, but in real life, it seems very subject to the lighting, and really seems more like a grey, that is a little blue. Except when you put it near something green. In which case - a little greenish.
This photo seems like the best representation of the colours I see in real life. The beads are two self-coloured spacers on the left and right, and over white in the middle.
And with a pure white background - looking more blue.
So this is one of those tricky colours that is going to be strongly influenced by the colours around it.
One of the things I thought was interesting was that the Effetre transparent greys look very purple when then are hot, and this glass did not do that - for whatever that is worth.
