M8 paper turns red or pink when it comes in contact with liquid nerve or blister agents. This color change indicates the presence of these chemical warfare agents.
The material you are referring to is likely a chemical agent detection paper called M8 paper. It is olive drab and treated with chemicals that change color when in contact with certain chemical warfare agents, aiding in their detection.
Persistent
Vesicants (blister agents) such as sulfur mustard and nerve agents such as sarin can be detected on surfaces using M8 paper, which changes color in the presence of these chemical agents. M8 paper is a reactive paper that turns red for vesicants and yellow for nerve agents when they are present on a surface.
Sarin is a nerve agent, not a vesicant blister agent. Vesicant blister agents such as lewisite, phosgene oxime, and nitrogen mustard cause blistering on the skin and mucous membranes. Sarin, on the other hand, disrupts the nervous system and does not primarily cause blistering.
