Sounds like a reasonable compromise might be to set a monochrome emoji font in the terminal. I think you’ve convinced me to try it.
I think lower-detail emoji versions (monochrome or with sparse use of colour) could definitely work better! Massive amount of work though, creating such a version for every possible emoji…
But you still want the warning emoji to be yellow, so you also have to add ANSI sequences around it.
