Aha, now I have lots of Prussian Blue!

Pp asked if there was anything I'd like him to bring back from his recent driving holiday in Scotland.  I said, 'yes, a tube of Prussian Blue'.
So he did.  Now I have lots of Prussian Blue, I painted this:

"Frodo and Sam halted and sat silent in the soft shadows, until they saw a shimmer as the travellers came towards them.

There was Gildor and many fair Elven folk; and there to Sam’s wonder rode Elrond and Galadriel. Elrond wore a mantle of grey and had a star upon his forehead, and a silver harp was in his hand, and upon his finger was a ring of gold with a great blue stone, Vilya, mightiest of the Three. But Galadriel sat upon a white palfrey and was robed all in glimmering white, like clouds about the Moon; for she herself seemed to shine with a soft light. On her finger was Nenya, the ring wrought of mithril, that bore a single white stone flickering like a frosty star. Riding slowly behind on a small grey pony, and seeming to nod in his sleep, was Bilbo himself."
