Hello ^^
There was several dozens pages ago a discussion of GOT7 comeback, 'You calling my name' or something, if I'm not wrong. A green ray of light surrounded the members, and this concept also appeared in SHINee's 'Lucifer' and 'Everybody' MVs. As for the GOT7 posts, someone said that the green color represents jealousy, Satan, and is also associated with the skin color of Osirirs (god of fertility, agriculture, the afterlife, the dead, resurrection, life, and vegetation). Green could be seen as reincarnation, vitality, life (maybe could be associated with Satan's lie of eternal life in some way, I think). The shade of green was different in SHINee's (a blueish hue) and GOT7's MVs, though.
Green could be also associated with the emerald stone, I am not sure of its MK-ultra meaning, but as for its occult meaning, I found this:
[...]contained the secret of Creation of Beings and the Science of Causes of all things. Hermetic tradition also maintained that an emerald fell from Lucifer’s forehead during his fall. According to medieval folklore, the emerald, placed upon the tongue, enabled to summon evil spirits and converse with them. However, it was also recognised as being able to heal some diseases, especially those pertaining to eyesight. [...] In the Apocalypse of St John, God appears surrounded by a rainbow “in sight like unto an emerald”. The Grail is carved from an enormous emerald. As the stone of occult knowledge, the emerald partakes, as do all symbolic objects, of lucky and unlucky aspects, benign and malign. Christian tradition drew a distinction between properties connected with the Heavens and with the Underworld, Good and Evil, and the blue of the sapphire opposed the green of the emerald. Nevertheless, the emerald is also the Papal jewel. In the Christian middle ages, certain Egyptian and Etruscan beliefs survived (such as the stone placed on the tongue enabling one to converse with evil spirits). Thus the emerald was the jewel of clairvoyance. In ancient Rome, it was attributed to Venus. In India, it was believed to impart immortality. The emerald is the expression of seasonal renewal and therefore it expresses the positive force of the Earth, of manifested life and of evolution. (source:

To this paragraph, I would add that since God is 'in sight like unto an emerald', green could signify Satan's wish to become like Him, and his fake promise to the people that they will be like gods. Also, I think that there was a passage in the Bible which describes God's throne as having green/blue stones at its footstool, therefore green could signify Satan's wish to take over God's throne. Green might be associated with one-eye symbolism too, in my opinion (keywords underlined in the paragraph above: clairvoyance, eyesight), as well as masonic duality (lucky and unlucky, benign and malign etc.). Also, BlackPink has that catchphrase, 'BlackPink is the revolution', this could relate to the meanings in the above paragraph in a way or another.
Hope this helped, and thank you for your thorough interpretations, as well
