Meet Pantone 448 C, "The ugliest color in the world"

According to Wikipedia, Pantone 448 C has been dubbed "The ugliest colour in the world."

Described as a "drab dark brown," it was selected in 2016 as the colour for plain tobacco and cigarette packaging in Australia, after market researchers determined that it was the least attractive colour. The Australian Department of Health initially referred to the color as "olive green," but the name was changed after concerns were expressed by the Australian Olive Association.
