What color is the Blue Line on the CTA map?

The Blue Line on the Chicago Transit Authority map is represented in blue. This color coding is a key feature of the CTA system, as each line is assigned a distinct color to help riders easily identify routes and navigate the transit network. The use of clear, different colors for each line enhances overall clarity and accessibility, allowing passengers to comprehend complex maps quickly and efficiently. This is an important design element in public transportation systems, as it contributes to the ease of travel for both regular commuters and visitors unfamiliar with the city. The other colors listed represent different lines in the system, further demonstrating the importance of accurate color representation for effective navigation.
