What's that discolouration on the silver spoon? (feddit.org)

I have my late grandpa's silver spoon attached to my fridge with a neodymium magnet. What kind of chemical reaction causes that discolouration?

That is a surprisingly not blue tarnish this photo provides no evidence

Reading comprehension... What even is it?

I do see that the light has mostly obscured a small band of blue so maybe its at a really neat phase of tarnish, but that's speculation and this photo provides no evidence that is actually the case. Either way, I really dont think the tarnish article goes far to actually explain the blue aside from describing the mechanism.

You sandwiched your admission that the photo showed blue tarnish on silver between a claim that the photo didn't show blue and the false claim that the OP specifically asked why blue in particular.

Your post started with "pictures of tungsten aren't helpful". This is proof you didn't read the Wikipedia article where it shows a silver coin with tarnish.

The OP didn't say blue. They said colorful. You brought up blue to deflect from you not reading the article that showed colorful silver tarnish.
