There are entries for the "DUMMY" role on the Display tab page under Status colors for catalog index. This means that the colors follow the condition entered here, thus overriding the standard green/semi-transparent color scheme.
When the Preferred series on/off [Preferred rows on/off] button is activated, red projects (applies if nothing else applies) and orange projects (standard part without ERP number) are hidden. Projects with an ERP number (yellow) and projects that occur at one location (light green), projects that occur at two locations (medium green) and projects that occur at all locations (dark green) are displayed. The color is inherited directly upwards to directories.
