1. Visibility: The most widely accepted theory is that yellow was chosen because it is the most visible color in both daylight and darkness. This makes it easier for potential passengers to spot an available taxi.
2. History and Tradition: The origin of yellow taxis can be traced back to the early 1900s when there were numerous automobile companies in New York City, each with its own color scheme for their taxis. To streamline the industry and make it easier for passengers to identify a taxi, the city adopted a single color for all taxis: yellow.
3. Brand Recognition and Marketing: Over time, the yellow taxi has become synonymous with New York City and is recognized worldwide as an iconic symbol of the city. The consistent color scheme helps create a strong brand identity and enhances the visibility and popularity of the taxis.
