What is Achromatic artwork primarily characterized by?

Achromatic artwork is primarily characterized by the use of white, black, and gray tones. The term "achromatic" literally means "without color," referring to a palette that excludes hues found in the color spectrum. This type of artwork focuses on tonal variations rather than vibrant colors or contrasts. Artists may utilize the nuances of light and shadow to create depth and form within the composition while avoiding the use of chromatic colors.

In contrast, the other provided options mention vibrant and bright colors or pastel shades, which do not align with the principle of achromatic art. Such artworks emphasize a minimalist aesthetic, often seeking elegance and sophistication through simplicity, rather than the emotional impact typically invoked by more colorful palettes.
