Compared to architecture and other kinds of design wayfinding has few ingredients to create a purposeful and natural flow through a room. Colour is an important one, and in that respect we have few rules and many possibilities, but when Triagonal ensures the wayfinding in international airports, we must obey to some guidelines: Bright green means exit all over the world, red is a universal sign of danger etc. Choosing the colour for the navigation of a venue is a question of adjusting to the rest of the design, and yet adding another layer to the general expression. We always work with colours that are easily recognised, because people should be able to say for example ’please, follow the purple signs’. That said, when dealing with airports we do make an effort to get the flavour of the country integrated into the colour scale we use in our work with wayfinding.
