I wanted to see what these look like, so I bought some on spec for a pair of charm earrings. They are a subdued grey-blue, definitely not an in-your-face colour, but quiet and elegant. It's actually kind of tricky to describe - it's a fairly dark colour, but the bead is very clear, unlike, say, dark indigo which looks nearly black. I suppose you'd say it's a 'low saturation' colour, as though the colouring agent is dark but they only added a little to the glass. The more I look at it, the more it makes me think of aquamarine mixed with black diamond. It'd probably go nicely with cream pearls for an antique look.
