Regarding this question: https://ux.stackexchange.com/questions/55326/what-is-the-color-that-reflect-new-york-city-most
This was closed as "primarily opinion-based" however it has a clear, easily stated answer and almost indisputable answer which I've placed in a comment.
The colors would most likely be those of the of New York are Orange, White and Blue as seen on the New York Flag. In addition these are used as the colors of the Islanders - NHL, Knicks - NBL, Mets - Baseball and NYC FC - Soccer.
It may, possibly, be off-topic for other reasons, but "opinion-based" it is not. Does this qualify for reopening?
