This is the yellow wall. Books are arranged by colour. It's called, colour blocking. It's not an intelligent way of arranging books but it is a colourful, decorative way.
So, yes, I am saying I don't care what the book is about or who it's by. I am solely interested in the colour of its spine.
Thus, with an infusion this evening of books of various colours, and more in the offing, I am thrilled. There is far too much white and black at present.
