Lack of color is a term used to describe a lack of vibrancy or saturation in a color. PALLOR, PALENESS, and ashiness are all words that can be used to describe this phenomenon. PALLOR is a six-letter word that refers to a pale or wan complexion, while PALENESS and ashiness are both eight-letter words that refer to a lack of color or hue. All three words can be used to describe a lack of color in a person's skin, clothing, or other objects.
