Bluish

Nardole claimed that "some of [his] best friends [were] bluish". (TV: Oxygen)
== Behind the scenes ==
The context in which "bluish" is used by Nardole does not make clear as to whether it simply regards skin colour or is in fact the name of a species. BBC iPlayer subtitles would suggest the former, as the word does not begin with a capital B.
Nardole's claim is an allusion to the popular excuse for denied prejudice, "Some of my best friends are... [insert group or identity here]".
This specific reference tracks to the line "Are you bluish? You don't look bluish", directed from one of the at The Beatles in the 1968 animated film . The original line was itself a pun on the comedy phrase "Funny, you don't look Jewish", which has its own historical connotations.
