Nah man, purple and green's the original aesthetic from green being purple's opposite. Applying purple exclusion filters onto imagery makes it that much closer to 'the look'.
Following that teal began to trend more, eventually replacing green in their purple-dominated designs, which then hit people in the late-80s to early-90s aesthetic with some of their old, forgettable corporate designs making a sudden comeback. Further along the teal inspired 'beach themes', drawing in tan highlights to suggest sand as it further fell into 80s chic.
Others who wanted to imply a darkness to it tend to go for high contrast grayscale with a purple color filter over it.
TLDR; It's about the purple.I didn't understand a fucking thing, but it was very interesting for me to listen to you. :)
I like purple
