The web color ghost white is a tint of white associated with what it is imagined the color of a ghost might be. There is no evidence that this color name was in use before the X11 color names were formulated in 1987.

Shades of white are colors that differ only slightly from pure white. Variations of white include what are commonly termed off-white colors, which may be considered part of a neutral color scheme.

In color theory, a shade is a pure color mixed with black (or having a lower lightness). Strictly speaking, a "shade of white" would be a neutral gray. This article is also about off-white colors that vary from pure white in hue, and in chroma (also called saturation, or intensity).

Colors often considered "shades of white" may include, among others, cream, eggshell, ivory, Navajo white, and vanilla. Even the lighting of a room, however, can cause a pure white to be perceived as off-white.
