On: Colour in the Middle Ages

[mananaysiempre]

I was taught that “green” (midori) is basically only for vegetation and things you want to say are similar to it. Even green apples are “blue” (aoi).

No, that's wrong. It's perfectly normal to use 青 for vegetation, e.g. 青葉. And it's perfectly normal to use 緑色 for everyday non-vegetation things (e.g. on a quick search I found clothes, cars, wallets...)
