I don’t have any books anymore. I took them all, several hundred, to Goodwill a few years ago. I hadn’t bought any in years because I’ve buying ebooks exclusively for a long time now. I have about 700 in my reader and almost any Internet connected device I have access to. My reading list is too long to reread anything, I thought others might get some use out of them.
Not having books in the house doesn’t mean what it once did.
To me it looks like the green from the iris bleeding in due to low resolution, not yellow.
