There are no other example paint schemes other than what has been shown in the supplements and webstore – mainly because Antares is far bigger and more diverse than a fair few other game universes. The armour is also highly adaptive/chameleo-active so alters to suit the environment.
Many units select as their base uniform colours those of a recent engagement or campaign in which they performed particularly well. My own Concord, for example, are in a Shamasai (sand-and-red-rock) based scheme and thee latest in a Taskarr (arctic) scheme; my Isorians are in a snow-and-blue-ice scheme. It also helps that the schemes can fit in well with my own terrain tables!
The Nexus is a great place for example paint schemes, though. Try https://www.gatesofantares.com/category/resources/showcase/ for a general list of showcase articles or try searching for ‘Ghar’ or ‘Concord’/ ‘C3’ (https://www.gatesofantares.com/concord-gallery/).
