I'm not a big fan of having Colors encoded into the EncryptionAuthenticity. Wouldn't it be better if we would use the Compound approach and replace enum Color { case red, gray } with an enum Importance { case primary, secondary } or similar?

[stefanceriu]

Okay, I now understand that this has been done this way to keep in line with the Rust implementation.

For posterity though, we belive colors to be inherently localisable and severity to be a way better abstraction.

Otherwise we can find ourselves in weird situations in which colors don't mean what we expect them to e.g. In China, red is auspicious—associated with life-generating energy (the sun, blood, and fire)—and is the color of celebrations and prosperity

[BillCarsonFr]

For context this is on purpose, and we want consistency across clients on how crypto shields/warning are represented(idealy same icons, colors, text).

[stefanceriu]

I understand, just pointing out that doesn't seem to be a winning approach seeing as how both icons and colors need to also be localized for the various cultures matrix/element will be used in.

Another random example:
UX designers need to take into account cultural differences when selecting symbols and colors. For example, while the color green is associated with life and growth in many Western cultures, it symbolizes death in some Asian countries
