Zeta uses a green base color on all war machines, accented with dark blue and white.

Clan Diamond Shark was known as Clan Sea Fox until 2985, and then again from 3100 forward. For units associated with the latter era, please refer to the Clan Sea Fox Faction Page.
The Clan Diamond Shark insignia is displayed on all war machines in the Clan Touman. Galaxy insignias may be painted on a ‘Mech or fighter, but always lower and smaller than the Clan insignia. Warriors with at least one confirmed kill may paint shark-like teeth in an appropriate place: the nose of a fighter, cockpit of a ‘Mech, front of a vehicle or faceplate of battle armor.
The Galaxy insignia is a pentagon, formed by the overhead view of five shark silhouettes against a muted aqua background.
