It's the sort of weekend where the creep of summer becomes noticeable. There are sunny spots to sit in (or to try to block out if they fall on your PC monitor). Here are some bits and bobs to read while you lounge.
This is not the Sunday Papers:
I have two ideas about that, both of which are touched on in the piece - one is that perhaps degradation over time distorts the colour of older paintings (there are studies which look at how blues might become grey, how varnish might react with pigment turning bright yellow to orangey-grey, and we know that paintings like The Raft Of The Medusa have darkened over time thanks to bitumen in the paint) another is the general problem of "blue" - both in terms of its historical expense and its durability and stability. That's just a bit of armchair theorising, though - Bellander invites interested readers to play around with the data and offer their own analyses.
