ORIGINAL PRACTICE PASSAGE
공통 지문A map that could be read without colour
1A youth centre needed a map for its open day. The design team marked every room with a different colour. During a trial, a visitor who could not distinguish some colours confused the art room with the music room.
2The team added simple symbols to the map to help visitors distinguish the rooms. It kept the colours, but each room could now be identified by both a symbol and a colour. The revised maps were printed before the open day.
3The change did not make the rooms larger or move them to different floors. It gave visitors another way to read the same information. A useful revision can change how information is presented without changing the information itself.
