Richard Cohen writes on ch 27 of: “Chasing the sun: the Epic Story of the Star that Gives us Life” Simon & Schuster, 2011.  

“Nabokov was unusually acute about the quality of sunlight, writing in his memoirs: ‘All colours make me happy, even the grey blood-orange Sun’ *

Has Nabokov cited Shade’s line 29 from “Pale Fire” in his memoirs?

* his note refers us to V.Nabokov’s “Speak,Memory”, Putnam, NY, 1966 (p.58 and p.44).
My edition is not by Putnam so I was unable to locate any “grey blood-orange Sun” while checking them in the book. Any clues or context about it?
