why do the cardinals jerseys look dirty

The Arizona Cardinals' jerseys look "dirty" because they feature a deliberate design inspired by their desert environment, specifically resembling sand- speckled or dust-stained patterns. This design approach is part of the NFL's new "Rivalries" uniform program, where the Cardinals' sand-colored jerseys and helmets aim to evoke the imagery of desert dust storms and sandy landscapes of Arizona. The intentional "dirty" or speckled look is a stylistic choice to represent their desert roots, although it has been divisive among fans, with some thinking the jerseys look like they've been splattered with mud or stains, while others appreciate the unique and thematic design. This look is meant to appear as if the players have been out in the dusty desert terrain, distinguishing these jerseys from the pristine and clean traditional uniforms.
