Firstly, thanks for sharing this - It would not have occurred to me to google something of this nature. I wonder how you even came across it / the subject line?
All the personal vanity aside for preferences, should this not be the ideal for most people given its been primed for that?
e.g. Yellow / Orange used for emergency / hazard safety - Is yellow the most conspicuous color? - Skeptics Stack Exchange.
Is this the first they have worked on and selected or have/ had they made some kind of preferred short list before this. I am sure before they designed this, they must’ve studied a bunch of candidates to take from.
