Color-Coding the books?

[rust]

It seems that right now the core books and the generic adventures have
black covers with the titles only, while the setting-specific books have co-
lour covers with their respective logos (e.g. Third Imperium, Babylon 5).

They are colour-coded

 

[Rikki Tikki Traveller]

The TMB has Traveller in RED
Mercenary has Traveller in GREEN
High Guard has Traveller in GREEN (but seems to be slightly lighter than Merc)
760 Patrons has Traveller in YELLOW

All on a simple, yet tasteful black background like the old Little Black Books (LBB) of Classic Traveller.
