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.
