Oh, I got why he was greenish, I just didn't know if he was back in the day or just in the remastered stuff. I think they should've continued with the subtle grren skin tint throughout, especially in TOS-R.I hate to bring this up but this might be the best time and place. In TOS-R, did they give Spock a light green tinge to his skin tone? In some episodes, it sure looks like it. It's cool if they did. It made him look more alien.
Spock's makeup did have a green tinge to it, and this was toned down as they refined his makeup.
Kind of reflected by the fact that he had green blood.
