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.

Trivia

 * The UNSC Prowler Wink of an Eye was said to have an "active camouflage skin" used to hide it from plain sight. As stealth ablative coating only hides a ship from radar, it seems likely that Wink of an Eye possessed photo-reactive coating as well.
