Lily Gao is a Canadian model and actress who has most recently been seen as the would-be U.N. Secretary General in the latest episodes of the sci-fi series "The Expanse" on Amazon Prime. (That's a show that's outside the scope of this blog, but I strongly recommend watching all four seasons of it. It just keeps getting better and better.)
Today, Ms. Gao is here to demonstrate the unifying theme at Shades of Gray.
