Navajo White is an orangish white color, or pastel yellow orange, and derives its name from its similarity to the background color of the Navajo Nation flag. The name "Navajo White" is usually only used when referring to paint. As the name indicates, the color is often considered a shade of white, even though it is more properly categorized as a yellow. In 1987, the color "Navajo white" was included in the X11 color list, which, after the invention of the world wide web in 1989, became known as the X11 web colors.
