In New York I also experimented with trying out relatively colorless photography, which I've never done before because I just never thought of doing it. (Clearly, I am full of interesting things to say!) Though below are the results, which I actually did end up liking (sorry for another skyline, but I couldn't help myself). I also made a short (very short) (very very short) (very very very short) (it's two seconds long) video that I will upload some other time, because I tried already and it came out not very well.
Color is like umami, because you can't explain it. How would you describe it to someone who had never seen before? Just like the meaning of umami is a "savory and pleasant flavor," I think "color" should have a meaning like "a fantabulously wonderful part of the way humans view the world."
