Color sensitivity refers to the ability of the human eye to perceive different wavelengths of light, which correspond to various colors. This sensitivity varies among individuals and can be influenced by factors such as age, lighting conditions, and the presence of color vision deficiencies. People with normal color vision can typically distinguish millions of colors, while those with conditions like color blindness may have difficulty seeing certain hues. In addition to individual differences, color sensitivity can also be affected by environmental factors. For example, ambient light can enhance or diminish the perception of colors, making them appear more vibrant or muted. Understanding color sensitivity is important in fields like art, design, and photography, where accurate color representation is crucial.
