I love this blue.
There was this beautiful blue bag I wanted to buy, in that exact same tone. It was large and nicely shaped and made of such soft leather. But I was undecided and the next time I passed by the shop it had been sold.
The effect is soft and misty even with the sharp tips of the tree branches and the rectilinear trunks. It's a bit like the effect you get in Photoshop when you duplicate a layer, blur the duplicate, and set it to "overlay" or "soft light" on top of the original layer.
