Here's an interesting skyscraper- 888 7th avenue, formerly known as the Arlen Building opened in 1972 and designed by Emery Roth and sons. I have to admit, I like the coloring on this one- that green stands out.
I do have to wonder though- was it always that distinctive color or has it gotten a reclad at some point?

Here's a picture I took on my most recent NYC visit:
