1. How do I start Colored Architecture? Colored Architecture works according to the server-client principle: Colored Architecture is the client (with GUI, calculation functions and visualizations) and the small ServerFive program supplied with it saves the data regardless of whether Colored Architecture crashes (hopefully this does not happen very often). The connection between the two programs is established via TCP/IP (network connection). This allows you to work on a model both locally on your computer and over the network.
