What a great concept.
LOVE IT!!! Soundcloud has the same system, using it as a placeholder while the images load (it might be random generated gradients though)
I was trying to think of the application then saw your comment. This would make for a great placeholder.
Google image search does the same thing. But only on mobile afaik.
This is neat!
FWIW, imgix can also do this, and can also output color info as JSON:
awesome. but I somehow get..
Traceback (most recent call last): File "gradify.py", line 3, in from PIL import Image, ImageFilter ImportError: No module named PIL
