The color 'nude' is defined as "flesh-color" in the dictionary. In fashion, 'nude' can be used to describe the color of anything from a shade of nail polish to Kate Middleton's iconic L.K. Bennett pumps. The nude high heels are a woman's must-haves, because they produce a leg-lengthening optical illusion, presenting a much slimmer look. However, since the color is often synonymous with Caucasian skin in fashion, people with skin of any other color are unable to follow this fashion trend. Couture shoe designer Christian Louboutin has created a brilliant solution to change that.

Nude high heels are known for the flattering quality that elongate a woman's legs, because they supposedly blend in with the skin color. If a pair of "nude" pumps blends with the color of a Caucasian skin, the same pair will contrast against darker skin. In other words, the skin of women from ethnic minorities won't be able to blend in with the default "nude."

Last month, Christian Louboutin, famous for the brand's luxury designs with red soles, launched his new collection called, "The Nudes." It includes five different shades of potential "nude" colors. The collection is designed to match a range of skin tones -- from the familiar traditional "nude" to a rich dark brown: fair to dark.

In addition, there is an app called "Louboutin Shades," where people can take photos of their feet and the app matches the skin tone to one of the five shoe shades.

"The shoes disappear like magic and become a fluid extension of the woman's legs, as in a sketch, elongating the silhouette," says on the Christian Louboutin website.
