Comparing side-by-side images of the Caribbean Sea and the Gulf of Thailand, most people would be hard-pressed to say whose water is bluer. The folks at holiday-rental agency CV Villas made that question a matter of science, not opinion.
The agency set out to determine which beaches around the world have the bluest waters. Its team sourced unedited images of 200 global beaches from Google Maps, generated digital color codes for each one, and cross-referenced those color codes against YInMn Blue, a shade discovered at Oregon State University in 2016 that’s touted as the bluest blue of all.
