why is boston wearing yellow

The Boston Red Sox are wearing yellow jerseys as part of their City Connect uniforms, which were introduced in 2021. These yellow and blue uniforms are designed to honor the Boston Marathon, one of the city's most iconic events. The colors and styling are inspired by the branding of the marathon, reflecting Boston's resilience and unity following the 2013 Boston Marathon bombing. The jerseys feature "BOSTON" in stencil font across the chest and the area code "617" on the sleeve, mimicking a racing bib worn by marathon runners. These yellow jerseys have become popular and a core part of the Red Sox's uniform rotation, symbolizing the spirit of Patriots' Day and the vibrant culture of Boston.
