Ukraine 2021(?)

[Suhiir]

The NATO (and incidentally Chinese) poison gas, biological, and fallout symbols are usually black on yellow.

Mines are typically black on blue (friendly) or black on red (enemy).

No blue or red for gas/bio/nuke cause they're not friendly to anyone!

GOOGLE "minefield warning signs"

You WILL see a lot of white on red.
You WILL see some that are black on yellow with the word MINES
You WILL see some that are predominantly white with a red border and a black skull

What you won't find is black on blue or black on red

So if you find some examples of these rare signs please do share
