I don't have a sharp sense when it comes to color. I try different ways to define a color scheme whenever I start an animation project. One of the ways I use is type a keyword into Google image search, capture a screen shot of the result, import into Photoshop and apply the Mosaic effect:
warning: There are scary pictures down there...
I typed "日本恐怖片 " (Japanese horror film) into the search bar, and the result is here:
(I mosaiced it a bit, because it's too scary :/)
I took a screen shot and import into photoshop, apply Mosaic effect:
And there you go! You got a Japanese style horror film color palette!
This is really fun to play with, so I tried different keywords to see the results. It's interesting to compare different region's horror films.
