I crawled lots of websites and extracted their color palettes (primary, secondary, etc) to build a searchable collection of website colors!
It was a fun side-project and I learned a lot about color theory. Let me know what you think and what features you would like to see :)
If you have any questions about the tech behind it, feel free to ask in the comments. Feedback is also greatly appreciated.
Allowing to chose proportions of colors could be even better.
Hypothetical example: Lets suppose that I'm a policeman. How much percentage of black, white and red is in a classical svastika?. Then browse the dark web for finding all webs that contain this particular white, black and red in such combination
Other possibilities: I want to know if my [bank/company/chess club] web is being cloned and used to criminal purposes without my knowledge. My logo contains magenta, lime green and burnt orange. Find me webs with this combination that aren't in a list of official webs from my company. Even better, check it at real time on email to spot scammers impersonating me on real time.
The applications are endless: I want to detect webs that sell fake clones of my products; or find photos of pills of a particular shade of blue. Or don't show me webs with a high content in warm tones associated with porno images...
Yep, that could be a really revolutionary startup.
