Uber completely revolutionized transportation aesthetics by adopting a severe, monochromatic palette of pure black (#000000) and stark white (#FFFFFF). This extreme minimalism strips away all visual noise, presenting the ride-sharing service as a highly premium, frictionless utility rather than a messy taxi company.
To alleviate the starkness and provide system feedback, the interface occasionally utilizes a supportive Safety Blue (#286EF2). The resulting design demonstrates how massive scale requires utter simplicity.
