tetracromáticas

Tetracromáticas is a term that can refer to several distinct concepts, primarily related to color perception and chemistry. In the context of color vision, tetracromáticas describes individuals, predominantly female, who possess four types of cone cells in their retinas, allowing them to perceive a wider spectrum of colors than the typical trichromatic human. This extra cone type, often sensitive to wavelengths in the yellow-red range, can lead to a richer and more nuanced visual experience, though the extent to which this is consciously perceived varies.

In chemistry, tetracromáticas can relate to compounds or pigments that exhibit four distinct absorption bands in the visible spectrum, or that are used in applications requiring a four-color system, such as printing. This allows for a broader range of reproducible colors. The term is also sometimes used in optical filters or dyes designed to interact with light in four specific regions. Understanding the precise meaning requires context, as it can apply to biological senses or material properties.
