Achroma

Achroma refers to a condition or concept of being devoid of color or pigmentation. It derives from the Greek words “a-” meaning “without” and “chroma” meaning “color.” In various contexts, achroma can describe a lack of color in biological organisms, such as albino animals or plants that have little to no pigmentation. In art and design, achroma might refer to grayscale or monochromatic palettes that utilize shades of black, white, and gray without the inclusion of hues. The term is often used in scientific fields, particularly in genetics and biology, to describe the genetic conditions that lead to a loss of color or variation in coloration among species. Overall, achroma encapsulates the idea of absence of color across different domains.
