Fun fact: They mandated all packages of snus (a "dip", or tobacco you put under your lip) sold in Norway must be plain and in this color. But it actually looks kind of good—very minimalist. So much so that people like this packaging more. (Image and source, Norwegian: https://www.itromso.no/ntb/iriks/2019/10/02/N%C3%B8ytrale-es...)
When asked how much they like the new packaging, 30% say "a lot" or "pretty well", compared with 20% for the old packaging. (Norwegian, https://www.nettavisen.no/okonomi/hoie-boksen-skulle-vaere-s...)
