Which term describes something that is colorless?

The term that describes something that is colorless is "achromatic." This word is derived from the Greek roots meaning "without color" and is commonly used in art and color theory to refer to shades that lack hue, such as black, white, and various shades of gray. The concept of achromatic color is significant in art as it allows artists to create compositions that focus on value, form, and texture without the influence of color.

"Chromatic" refers to colors and the spectrum of hues, which is the opposite of being colorless. "Polychromatic" describes something that contains multiple colors, and "monochromatic" means consisting of or displaying one color or variations of one color, thus not relating to colorlessness. Understanding these definitions is vital for comprehending various color theories and their applications in art.
