Dark Camouflage (3.5e Equipment)
From D&D Wiki
 Dark Camouflage
This kit consists of loose-fitting garments and jars of impermanent paint. Its items are colored the darkest and dullest black. The clothing can be worn over armor and the paint applied to any portion of the body. When in the cover of night or low-light areas, characters using this kit gain a +2 circumstance bonus on Hide checks. Illumination and creatures with darkvision render this kit useless. Camouflage kits are exhausted after ten uses. Each use lasts until the garments are removed and the paint is washed away.
