That's why you don't just use colour for identification. E.g. include a warning icon next to a button/element in addition to using a warning colour.

Nor just shape, so a warning icon + text message.

and, as is being increasingly forgotten, SOUND QUES. Seriously, I get they can be annoying but they make navigating and interacting with things so much easier if you can't see them. Sure, TTS exists but is far more inefficient and objectively less helpful in these kinds of circumstances

Another great example of increasing accessibility while reducing usability.
