Flames of Kindred Spirits
The standard paint scheme for the Ghost regiments begins with a base coat of gray so light that it appears almost white. Accenting is usually white or darker gray. The Tenth Ghost paints its 'Mechs light gray with dark gray striping. To honor its yakuza heritage, the regiment decorates it vehicles with painted blue flames, which also denote a unit member's faction affiliation. Members of the unit's original two factions paint the flames all along their 'Mech's right or left sides. Members of the newest group paint the upper halves of the BattleMechs to resemble flickering blue flame.

The Ghost regiments do not have a regimental crest, as that designation serves as an administrative classification more than anything else. Per FM: Draconis Combine, page 112.
