In everyday context yes, but it’s pretty common to use “colour” to refer to frequency outside the visible range, and it’s interesting to consider what interesting “colours” we are missing out on because they’re outside our visible range.
Silver/grey implies even response across the spectrum, and is the normal expectation.
If we couldn’t see yellow (red/green) then gold would presumably look silver to us, so are there silver/grey metals that would have an interesting colour if only we could see it?
The fear seems to be that access to guns quickly leads to normalisation of guns, especially if the criminals try to keep up.
But I can imagine a middle ground where guns and training are available, but you have to get permission from a specialist who’s on the hook if it turns out the guns weren’t justified (or some such idea to stop them ending up in every action) to unlock the gun safe. Then the “domestic with a shotgun” scenario might be resolved a little more efficiently without everyone having to accept guns everywhere.
