Pink skin

From Memory Alpha, the free Star Trek reference

Pink skin was an Andorian slang term for Humans, in reference to the 'pink' skin color of some of the first Humans that they had encountered. It can be a deragatory, neutral, even polite phrase, depending on the context in which it is used.

The phrase was used many times by Shran and once by his daughter, Talla. (ENT: "The Andorian Incident", "Shadows of P'Jem", "Cease Fire", "Proving Ground", "Zero Hour", "Kir'Shara", "Babel One", "United", "The Aenar", "These Are the Voyages...")
