The show had already established how Tendi has green blood earlier in the series after an injury and it would have been an easy to infer detail compared to humans in the show.
Other animated shows like Steven Universe already show how non-pink blush colors can work in animation.
I feel like a lot of it is “translated” to match human emotions. That person wouldn’t actually be considered attractive, but the movie makes them attractive in a weird way so humans can relate. Green lipstick on a Vulcan would be EXTREMELY off putting to a human, in literal stark contrast. To make a Vulcan “attractive” it would be on human terms with our sexy red lipstick or… it may have the wrong effect and not tune emotions in properly to the scene. It’s a huge reason why I hated watching Star Trek with a particular individual I know. “THOSE TWO SPECIES COULDN’T BE BREEDING! THE HORMONES ARE ALL WRONG AND THEY DIDN’T DEVELOP IN THE SAME…” and on and on.
The blushing thing absolutely should be green, but I get why it wasn’t characterized as such. Friggin apes.
not the biggest fan but doesn’t TNG suggest that all (most?) biped races in trek share a common ancestor?
Yes it does, i think there is a tos episode that hints at that as well
