Pink, more than a color, is also a verb meaning prick for instance to produce a pinprick, apparently for writing anciently because the Turks (progeny of Togarmah’s son Turqi) used pink or pik (pick) to mean write or paint, which jibes with that two millennia later, fellow indo european (japethite) the roman Pliny wrote that a black ink was a kind of painting made by burning on wood.
