Baby blue in human culture
In Western culture, the color baby blue is often associated with baby boys (and baby pink for baby girls), particularly in clothing and linen and shoes.

In the late 1960s, philosopher Alan Watts, who lived in Sausalito, a suburb of San Francisco, suggested that police cars be painted baby blue and white instead of black and white. This proposal was implemented in San Francisco in the late 1970s, until the late 1980s. Watts also suggested that the police should wear baby blue uniforms because, he asserted, this would make them less likely to commit acts of police brutality than if they were wearing the usual dark blue uniforms. This proposal was never implemented.

Baby blue is an official color used in the flag of Argentina.
