Photoreactive panel

Photoreactive panels are a form of active camouflage developed by the United Nations Space Command. The outer layer of the Semi-Powered Infiltration Armor is coated with photoreactive panels to hide the wearer from sight. While not as sophisticated as Covenant active camouflage, the technology advanced during the Human-Covenant War, with the newer SPI generation being fitted with more efficient photoreactive panels in 2551.

UNSC Prowlers are also equipped with a form of photoreactive paneling, integrated to the stealth ablative coating and enabled by texture buffers.
