What color are standard CTA bus service maps?

The standard CTA bus service maps are blue. This color is consistent across various materials provided by the CTA and helps users easily identify bus routes and connections throughout the transit system. Using a distinct color for maps aids in enhancing visibility and differentiation from other transit-related documents, ensuring that riders can quickly find and utilize the information they need for navigating the bus system efficiently.

Additionally, specific colors are associated with different types of transit services, and blue has been chosen for bus maps due to its clarity and legibility in both print and digital formats, which are essential for user-friendliness in urban navigation. The use of blue also helps create a cohesive design across the CTA's materials, allowing riders to more readily understand the various services the CTA offers.
