Side note: agree with all this except

> Red is a warning color

That is definitely the case in western culture, but in places like China, red is a positive color. Always interesting to learn what are universal signifiers (like up for more) and what are culture-specific signifiers!

Deepseek's iPad app has widgets (buttons labelled "Search" and "DeepThink") that are black in the "off" state and blue to indicate the "on" state.

is it why in China drivers run red lights so often? they should really recolor them if what you say is true
