Selected modules come with what is called a halo effect. Two types are available: classic and alternative. The halo type is set in the Preferences, see Section 4.3.7, “Preferences — Network Appearance”.

Figure 3.13. Halo Appearances — Classic and Alternative

The classic halo shows a weaker halo for attached modules; the alternative halo shows the same strength for all modules. For the selected and the attached input and output modules, different colors can be set in the Preferences to make their roles more visible.

If an attached module is input and output module of selected modules at the same time, the halo color will mix. With classic halos, just the average color of input and output attached module is used. Alternative halos are rendered in both colors as shown in the figures.
