Visor color

In Halo: Reach, in addition to customizing armor, the player can customize the color of their visor. As with all armor permutation options, visor color is purely cosmetic and has no effect on gameplay.

Trivia

 * The description for the silver visor is a reference to Orbital Drop Shock Troopers, who are frequently associated with the phrase "feet first into hell". In Halo 2, ODSTs wore helmets with silver visors. However, in Halo 3: ODST, most ODSTs wore helmets with bluish-grey visors, while Veronica Dare wore a Recon helmet with a gold visor.
 * Changing the visor color of the Haunted helmet will instead change the color of the skull.
 * Both Jorge and Jun have a red/orange visor, so it's odd that this color can't be used.
