Porto, Portugal. Porto has every imaginable type of transport from funicular to little ferry boats. Here is the logo for the metro system.
The metro uses ColorADD, a color system designed by Portuguese graphic designer Miguel Neiva for colorblind users. Symbols are used for each color, combined in pairs to represent secondary or mixed colors, based on subtractive primaries. This system is used in Portuguese hospitals, schools, traffic lights, packaging, etc.
