Why are so many umbrellas black?
When umbrellas first came into greater use during the 18th century, they were made of oil-soaked cotton cloth that was stretched over a whalebone. The purpose of the oil was to make the cotton cloth water proof, but it also gave the cloth a black-looking color. While this type of umbrella was very waterproof, it wasn’t very durable. Soon, newer and better umbrellas were made, and since the color black was associated with effective waterproofing, most of the newer models were dyed black.
