This isn't just a colour on the copper fixture — the same copper carbonate that turns the metal itself green has washed down and tinted the stone beneath it, a visible record of ongoing oxidation.
The exact shade of verdigris varies with humidity, pollution and how long weathering has continued — this is one specimen at one point in its exposure, not a fixed reference colour."Verdigris" by Alex Liivet, CC0, via Wikimedia CommonsLicence details

Colour stories
Why a copper roof or statue turns green over decades, not days
Verdigris forms as copper reacts slowly with oxygen, moisture, carbon dioxide and airborne sulphur compounds — a process typically taking years to decades outdoors, not a sudden change. The exact shade and speed depend on local climate and pollution, which is why two copper structures in different cities can weather to noticeably different greens on different timelines.
In practice: There is no single 'verdigris green' reference colour — the same starting material weathers differently depending on where it is, which matters when specifying an aged-copper finish.
