What is the term for the defect in color perception?

The term for the defect in color perception is Color Vision Deficiency. This encompasses a range of conditions that affect an individual's ability to perceive colors accurately. It is a more encompassing term than "color blindness," which is often used to refer specifically to the more severe forms of this condition where a person cannot distinguish between certain colors.

Color Vision Deficiency includes various types, such as red-green or blue-yellow deficiencies, which can affect individuals to different extents. Recognizing the nuance in terminology is important, as it helps clarify the specific nature and severity of the perception issue.

Using terms like "Hue Perception Disorder" is less common in the clinical and academic communities, and "Visual Acuity Deficit" pertains to issues with sharpness of vision rather than color perception. Thus, Color Vision Deficiency is the most accurate and widely accepted term to describe defects in color vision.
