I saw this billboard and thought to myself: How’d they do that?

Maybe you figured it out instantly and I was having a dumb day, but it took me reading that they cut roller shaped parts out of the board, so no matter what colour is behind it, they match. Quite clever in my book and definitely caught my attention.
