It's not even a log scale, there's a 0 on there. The scale is all over the place.

It's not so much representing them in RGB that is a problem, you could do it with negative values if you really wanted to. The main problem is that the computer monitor wouldn't be able to display them accurately, which I reckon is most of the value Pantone added, colours with fixed IDs that have some kind of physical reference so you know what they end up looking like even if your display says otherwise.

A sim the attacker knows the PUK code of.

Yep, though you should always be careful what mechanisms you allow to be used to ban stuff. It's no surprise they're trying to use laws designed for terrorist and child sexual abuse, those are often the ones used as justification for mechanisms that would seem excessively authoritarian otherwise (those and money laundering).

The danger with allowing tools like this to exist is always that people get weird ideas about what other things they can be used for. Doesn't matter how loudly anyone promised they'll never be used for anything else.

There's exactly one kind of colour space where blending colours makes any sense and it's the ones where colours are a simple linear transformation of the light spectrum. For humans you'll want to use either CIE XYZ or CIE RGB (the end result is equivalent). In these spaces blending colours has the same effect as blending light of the same colour, which is usually what you want.

If you use non-linear spaces you're not blending you're 'tweening' colours at best, doesn't matter if the space is perceptually uniform or not. This can be helpful for graphic design, but it's not physically meaningful and usually has some weird edge-cases.

Surely inflation is expected to go down at some point? It seems unlikely that prices would continue to increase rapidly indefinitely.

Of course we wouldn't suddenly get a large spike of deflation as prices go down again, wages are already adjusting to the new price point which means it's probably stuck for now (not necessarily a bad thing, to some extent it's the economy fixing itself by devaluing old money).

Inflation is the derivative of the price level though, it would be weird for inflation to stay record high two years in a row.

Also 'difference with 12 months ago' is useful as a metric, but behaves a bit oddly when you want to estimate the derivative of something that changes rather quickly. It doesn't filter out high frequency stuff, it mostly just filters periodic patterns that repeat yearly.
