>The scene is from the story of the warrior-hero Minamoto no Yorimitsu (948–1021) who, once when sick, was visited by an evil priest in the guise of a giant spider. Yorimitsu saw through the disguise and attacked the spider priest, and his four attendants (who were playing a game of Go while guarding him) leapt up to track the intruder back to his den

That's... an interesting thing to put on your fire coat. I bet a lot of modern departments would love these. They are all about identifying as their individual groups and taking pride in being a team. Aramid is naturally the yellowish color that bunker gear already is but can be dyed, although you might have issues with fumes from the dye being heated in fires.

You could skip bunker gear entirely though and just do a startup making custom jackets like this. The aramaid used for bunker gear is woven so just develop a machine to weave using x number of colored threads and do fairly simple patterns like this. This would beat the heck out of embroidered jackets for teams/agencies/social clubs too and you could even resurrect some historical art like this spider. There's already computerized embroidery, computerized custom woven jackets would be awesome. Forget "ugly Christmas sweaters".

In the past beautiful patterns and designs in textiles showed pride and wealth, now a name sewn on the label does. Resurrecting stuff like this with tech, so that it is affordable to the masses, would be an awesome thing.
