Glad to see some bismuth love, but c’mon.
I shoulda got my class ring in Bismuth instead of bloodstone…
I wonder if there are some metals that appear grey to us but actually have a color, we just don’t see it because it’s outside our visible spectrum
… when charged particles move faster than the speed of light
So that got me curious, and found this
nothing travels faster than light in vacuum, but light can be slowed down and something can travel faster than this “slower” light
Somehow I’ve gone through decades of life without knowing this…
That is the very definition of colour. The part of the electromagnetic spectrum that we can see. The rest of the scale includes infrared, gamma or X-ray. If you want, you can call them invisible colours - or you can call green superhighultraviolet.
Well infrared goes the other direction. Along with radio.
If a bee sees a color we cannot, it would be pretty silly to insist it’s not a color on the basis of us being unable to see it, wouldn’t it?
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?
Bi pride?

What about pyrite? Or Iron Maiden?
Pyrite isn’t a metal. It’s an oxide.
That’s what it wants you to believe.
And it makes your tummy feel better. Bismuth master race
and smell better too

The top two houses are in LA at the beach, no?
Not sure why, I don’t even live in the US, but I recognize them
