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

There are multiple examples of the colorful toning in the article I linked. So you appreciated the link, but not enough ot actually look through it.
Pictures of tungsten tarnishing aren’t helpful when op is talking about silver. Stating “thank you, that’s the general idea yes, but I was trying to ask more specifically” isn’t an attack on you. You don’t need to defend yourself.
Right below the picture of tungsten is this picture of a silver dollar.
That is a surprisingly not blue tarnish, if its supposed to explain what OP is showing us, if it makes a point, please help me comprehend.
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.
Reading comprehension… What even is it?
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.
The photo is proof that silver can tarnish to blue.
I read everything. (Even changed to my mother tongue.)
Didn’t find anything about interactions of different metals. It only said something about interactions of metals and non-metals.
