Very useful to spot webs with a particular theme, blue webs, sunny webs... but also all webs from a particular logo or party that often use the same palettes again and again as brand image.
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.

Haha, lots of great ideas! I'm definitely considering adding an option to search by color proportions, just trying to find a UI/UX that is not confusing for people.
I also have a lot more content (i.e.: the full HTML code of the website, the fonts and typography options) that I extracted for each website but it's tricky to come up with an easy to use UI/UX for this as a search filter, given that there's not many other websites that do this.

It's a neat idea, and bookmarked it just for ideas on possible designs.
Weird parts though. Does not ever seem to return a website I have ever heard of. And (although it may have nothing to do with you, and everything to do with the modern web) a lot look rather algorithmically designed.
Plus, there's sites like these people: https://www.beltnbags.com.au/ that register on every pure tone and near pure-tone search because they're listed as (#0000ff, 24.9%, #f7f7ff, 13.0%, #f7f7f7, 13.0%, #00ff00, 24.2%, #ff0000, 24.9%)
However, if you go to their website, I don't know what you're scraping, cause it sure does not "look" like its 1/4 red, 1/4 green, 1/4 blue, and 1/4 of dueling eggshell white. It looks white, black, teeny red labels, and lots of brown clothes.

There are definitely some odd ones. The screenshots were done a few hours after the initial crawl, some pop-ups may have appeared on the first crawl.
The crawler also blocks image loading (to not take image colors into account because it's screenshotting the entire page and creating a frequency of each color from the screenshot, pixel-wise) so it's possible that some fallback CSS was displayed instead of the images.
I definitely have to refine it more and it's far from perfect. There are only ~25k websites indexed and I used a list of 1M most popular websites created by the developers of a Chrome extension, based on what most people were visiting.
I tried my best to sort by popularity but I'm sure that the list is not perfect. Plus, some websites are really unfriendly to crawlers and, as much as you try to hide it (by faking user agents, using realistic window dimensions, proxies, etc.), some will still detect you.

Just playing devil's advocate, there are a LOT of domains out there. A quick search says there's still well over a billion websites on the internet.

Totally realize there's a lot of websites. Just figured with fairly simplistic color tone choices, you might get something like Google 'occasionally'.
Google as example: Current logo: #4086F4 (blue), #EB4132 (red), #FBBD00 (yellow), #31AA52 (green). Google (at least on my search) only shows up as a leftover of somebody else's search. Of course, there's also only 9 results.

This is really cool. We've recently built a website catalog (https://www.rapidpages.com/inspire) and one of the difficult choices we needed to make was whether to include images on the site or not when extracting the color palettes. I'm curious if you've also experimented with this?
The site is looking great! I think that screenshots are a must, it's a lot easier for the end-user to preview the website's content. If you're referring to screenshots where certain colors are used, I don't think that's necessary.
The first version of it, I didn't take any screenshots and it felt very empty. It's a bit hard to manage the images and deliver them rapidly, in an optimized form, but I think it's worth it.

Oh, I was referring to calculating colors used on a website. To give you an example, we've stumbled upon pages where there's a product on the page that contained the color red, and nowhere else on the page was anything red. Our naive approach to finding avg colors was to simply take a screenshot of the page and process that image. Unfortunately, this method produces inaccurate results like red being part of the average colors when the design system has no red. I was curious if you managed to work around this issue.

Ah, sorry, I understand what you mean now. Yeah, I've also filtered out images when calculating the color percentages and there are definitely some funky results.
There's definitely a middle-ground approach here, I just haven't found a good enough heuristic. It's true that images are part of the branding and they impact the color palette, like banners and logos, so they should be considered in some quantity. I thought of maybe averaging the results of image/no image but I don't have enough test data to validate it yet.
Let's chat and discuss more! I'll also add you on Twitter/X

Great Stuff, I could imagine this being handy when looking for design inspiration.
Haha, thanks! That's exactly what I had in mind when building.
I've also collected what fonts and typography styles different websites use so I'm looking to create a visual for that as well, thanks for the feedback!

I wonder if you open up this to also deconstruct color variables (-var) into their respective hex codes if you'd get more results of sites that use design systems.
Have you explored that much at all?
Cool project!

That's a really interesting idea that I didn't get to experiment on, unfortunately. It's currently screenshotting each crawled website and extracting the colors from the pixel values.
One filter I added to make the palette a bit more relevant is that I try to find out which is the background color (the most used color) and only pick colors that are at least somewhat contrasting with the background (assuming that websites would follow somewhat basic color contrast rules).
When I tried extracting the palettes from CSS rules, what I ran into is that each website uses lots of vendors that render stuff (cookie consents, promotional pop-ups, etc.) and it's hard to distinguish what's rendered and what's not with pure CSS selectors, so I resorted to decomposing the website's theme from the perspective of a user. (through a screenshot)
It's a great idea nonetheless, I'm sure I would have some good results with it if I manage to filter out the noise, thanks a lot!

I was looking for neon green sites for inspiration... Google says this site is now badware:
millionfollowersbootcamp[.]com
millionfollowersbootcamp[.]com
Yeah, I need to curate the existing list of websites and perhaps swap the existing list for one with more popular websites. I'll definitely have a look, thanks!
Finally, I can see who is using this years Pantone style guide!
Reeeally loving this one, great job !!
Amazing. Maybe you can show the chosen color as the background of the hex code?
That's a great suggestion, will definitely do that in the next iteration. Thanks a lot!
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 :)
