Selected modules feature 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”.

Table 3.31. Module Halos — 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 distinguishable.

If an attached module is the input and output module of the selected modules at the same time, the halo color will mix. With classic halos, those modules have a white halo. Alternative halos are rendered in both colors, as shown in the figure on the right.
