This prestigious ranking is published by JustCover – a reputable travel insurance brand based in Ireland, in collaboration with data analysis from Condé Nast Traveller magazine. The primary methodology of this ranking is pixel-level data analysis: using algorithms to extract and measure the number of unique colors from a large-scale image archive (satellite images, skylines, architecture, and everyday life) in nearly 80 cities worldwide.
Accordingly, Hanoi's color palette is considered sophisticated in its diversity: a multi-layered structure where "visual language" is expressed through artistic contrasts.
The vibrant heart of Hanoi lies in the Old Quarter. From a pixelated perspective, the "chaos" of thousands of signs, closely packed shops, and winding motorbikes is not chaos, but a "living visual language" that demonstrates the economic prowess and dynamism of its local inhabitants.
The warm colors like red and yellow of the lanterns and billboards are not separate but blend together, contrasting strategically with the quiet gray-blue spaces of moss-covered tiled roofs, tranquil temples, and ancient trees.
The colorful heart of Hanoi lies in the Old Quarter.
From images of tourists sitting by the train tracks in the heart of the Old Quarter to the narrow, winding alleyways, Hanoi's color palette is a blend of the distinctive yellow paint of French colonial architecture and the vibrant rhythm of a modern East Asian metropolis. This is what is highly appreciated: Hanoi's colors are not the colors of fresh paint, but the colors of life constantly moving on a foundation of heritage.
Because of the strict requirement for authenticity, only original, unedited photos are included in the measurement system to ensure that the "vibrancy score" accurately reflects the reality of the landscape. As a result, the evaluation can be considered very objective, and the charm of each destination is proven by the numbers.
Ranked 8th out of 10 globally, Hanoi achieved a vibrancy score of 69/100, recording over 1.8 million unique colors.
The colorful city of Lisbon (Portugal).
While the top-scoring city, Lisbon (Portugal), achieved a perfect 100/100 with 2.63 million colors from its multicolored azulejo tiles, yellow trams, and pastel walls.
Kuala Lumpur (Malaysia) came in second thanks to its vibrant colors from futuristic architecture interspersed with Hindu temples and a multicultural market. Porto (Portugal) took third place with its dazzling color palette along the Douro River and ancient Iberian architecture.
Also making the list are Cartagena (Colombia) for its vibrant Latin American style with dazzling facades, Rio de Janeiro (Brazil) with its hot tropical colors from favelas and beaches, Guanajuato (Mexico) with its colorful terraced houses characteristic of Central America, and Medellín (Colombia) with its modern art murals in a city undergoing renewal.
Havana, Cuba's capital, contributes a nostalgic palette of colonial buildings and vintage cars from the 1950s, while New Orleans (USA) offers a blend of French, Spanish, and Caribbean cultures.
Hanoi's visual heritage is an invaluable asset.
Being in the Top 10 is not just a number, but could be a strategic "lever" for the capital's tourism industry in attracting high-quality tourists – those who follow the Experiential Travel trend, always seeking authentic and emotionally rich cultural values.
Hanoi's visual heritage is an invaluable asset, perfectly complementing the message of "Green Tourism Journey" and the image of "City for Peace." Its vibrant urban landscape is part of its "soft power," making Hanoi an irreplaceable destination for international tourists.
Maintaining a diverse yet harmonious color palette, without being homogenized by soulless glass and steel architectural structures, is key to Hanoi's unique competitiveness on the global tourism map.
