The world’s most colourful cities revealed
- New research reveals the global destinations that offer the most varied spectrum of colours, based on image analysis
- Lisbon tops the ranking, with over 2.6 million unique colours identified, followed by Kuala Lumpur (2.5M)
- Porto claims third place, making it another Portuguese city to stand out for its visual appeal
Some destinations are renowned for their vivid aesthetics, whether it’s the blue streets of Chefchaouen or the electric buzz of New York City, offering striking backdrops for travellers. And in an age where travel is increasingly documented on social media, the visual appeal has never been more important. But how do these iconic destinations compare when their full visual spectrum is put to the test?
To find out, a new study by Irish travel insurance specialists at JustCover analysed images of 78 destinations well-known for their vibrant colours and measured colour variation using pixel-level data.
Lisbon takes first place as world’s most colourful city
To examine the vibrancy of a destination, representative images for each location were selected to reflect the typical scenery, taken in clear daylight and without heavy filters. A colour analysis tool was then used to identify the number of unique colours in each image, revealing the most vivid destinations overall.
Across the top 15, the Americas come out on top, including Guanajuato, Havana, New Orleans, Antigua, and New York City. These cities stand out for their vibrant architecture, bustling streets with dazzling signage, and neon lighting. However, Europe is also well-represented, with two Portuguese cities in the top three, as well as Dubrovnik and Barcelona ranking highly.

Lisbon ranks as the world’s most colourful city, with more than 2.6 million unique colours identified in the analysis.

Kuala Lumpur ranks second, with a striking contrast of modern skyscrapers and traditional buildings, including ornate temples and shrines. The city’s Chinatown is a popular destination for tourists seeking the vibrant street life, filled with lively markets and tempting street food. The rainbow-coloured steps of the Batu Caves are frequently associated with the destination, and while not located within the city itself, they’re just a short drive away.

Porto places third and is the second Portuguese city to rank for its colour variance.

The port city of Cartagena has long been famous for its rich colours, with the yellow Clocktower at the main entrance of the Old Town a standout sight of the city. Rainbow-hued buildings line the streets, while flower-filled balconies further add splashes of colour to the already vibrant city.

Rounding out the top five is Brazil’s second-largest city: Rio de Janeiro, with over 2.3 million unique colours identified
Aaron Brennan, Director at JustCover Travel I
“It’s not just architecture; even busy urban centres like Kuala Lumpur or New York City impress due to dense signage, billboards, and neon lighting, which increases the visual variation captured across the cities. It’s also encouraging to see some Irish cities rank highly too, which may not always be the first destination to come to mind, but highlights the beautiful aesthetics that can be found closer to home too.
“Whether travelling long-haul or just hopping on a short flight, trips don’t always go to plan, so it’s important to have the right cover in place before you book your trip, to help ensure maximum protection. It’s also important to check current travel advice from official government websites, as travelling against guidance can affect or limit insurance cover.”
