1. Pale, pallid, wan imply an absence of color, especially from the human countenance. Pale implies a faintness or absence of color, which may be natural when applied to things, the pale blue of a violet, but when used to refer to the human face usually means an unnatural and often temporary absence of color, as arising from sickness or sudden emotion: pale cheeks. Pallid , limited mainly to the human countenance, implies an excessive paleness induced by intense emotion, disease, or death: the pallid lips of the dying man. Wan implies a sickly paleness, as after a long illness: wan and thin; the suggestion of weakness may be more prominent than that of lack of color: a wan smile. 5. blanch, whiten.
