Editing Orc (section)

=Green Skin=
One usually wonders where the green coloration of Orcish skin came from, in the old myths (i.e., Lord of the Rings) the orcs were established as barbaric, crude brutes, true; but the approximate skin color was never truly established, the Orcs were generally described as filthy and mucky, with darkened skin and bestial countenances. (Similarly, in the films their skin shades are in varying shades of ash-black and dirty-brown, the occasional bit of face-painting notwithstanding.) It wasn't until the advent of the Hulk comics, and GW deciding to make their orcs different, that the common skin of the orc became green. Because Warhammer's orcs became so memorable, thousands of copycats have followed suit.

This of course may not truly explain why some orcs in DnD have green skin as well, DnD being around before Warhammer, but the a more precise green coloration in its orcs may have come later. Indeed, earlier DnD art shows a variety of skin colors, some of them sallow yellow and earthy reds. Green may have come about because all the other possible colors simply have clashing connotations, such as a calming blue, or offensive real world racial connotations (black, [[kobold|red]], brown, and [[goblin|yellow]] are right out for a barbaric and evil race of XP bags.) Another theory is that Ian Livingstone and Steve Jackson, the 2 co-founders of [[Games Workshop]], also had a lot of communication with Brian Blume, the developer of D&D, especially in the early days of these 2 companies, so it is entirely possible that certain ideas were mentioned and then copied.  For what it's worth, D&D orcs are grey as of 5e, not green. Seriously, open your monster manual if you don't believe us.

''In-universe'' reasons for their chartreuse complexions vary between IPs; While earlier editions claimed that the Orks of 40k are said to be animate plants, current lore dictates that Ork DNA is a combination of animal, plant, and fungal DNA, thus their colors are effectively the result of chlorophyll running through their bodies (while the animal part conveniently allows them to bleed red). Meanwhile, the green skins of the orcs of The Elder Scrolls and Warcraft universes are the result of demonic tampering; The Orsimer are a result of the above-mentioned champion-devoured-and-shat-out incident, while the Warcraft Orcs were convinced to drink the blood of the Pit Lord Mannoroth, changing their normally brown or grey skin into that distinct hue, with further ingestion of Pit Lord blood turning them red. Some orc clans turned down the offer however, and still keep their original skin tones in the present.
