It was not allowed to put or draw any stuff on the wall in my graduate school. But white walls, which looks like canvas, have been waiting for creative ideas of students. So I decided to fill walls with cheerful signs.
Simple images can be understood easily and clearly while chatty words express the vitality of the school.
Each different color shows its function. Magenta signs are for academic places. Lime signs are for toilet and locker. Yellow signs indicate basic school facilities and a sign for fire extinguisher is red. Emergency exit must be green because of the universal notion.
