The most noticeable is the lighting on One World Trade Center's spire - it's lit up in blue, white and red in honor of the victims. This was an order by New York Gov. Andrew Cuomo, who said it shows New York will stand with the people of France.
The 408-foot spire will be lit up Friday night and in the next several days.

While the Empire State Building went dark in sympathy of what happened in Paris:

New Yorkers are remembering the victims of the attacks in other small ways. One heartbroken resident brought three yellow roses to the French Consulate on Fifth Avenue in Manhattan.

An another woman lit a candle in front of the consulate:
