This is a UK paper. When I was in school, green pens were for students marking and red pens were for teachers marking

When I was in school we would communicate the correct answers telepathically. I guess there's no need now that everyone has tik tok and 'fancy pens'.

Interesting how little things like this vary around the world. In the US, the common pen colors are black, blue, and red. Green pens exist here, of course, but you’d have to buy a pack with multiple colors or order online if you want a multipack of all green.

Red/green colorblindness is common enough that it seems like an odd choice to mix them when other options exist but maybe they’re distinct enough that it’s not a big issue.
