I see these types of questions as the sign of an inexperienced interviewer. Given how many inexperienced interviewers one can see interviewing at tech companies, I would call that a chartreuse flag at best due to lack of signal.
Props to both of you for the lovely synonyms for "greenish" :-)
(And as for the substance: agreed, and a capable interviewee should know how to work around those questions and similarly silly ones, like "what's your greatest weakness?". It's a two-way street. And while it's not a positive datapoint, it's hardly a KO-criterion. (viridescent? aquamarine? turquoise? :) )
