2024年8月14日 · Tetrachromacy is a rare ability that gives people assigned female at birth (AFAB) extraordinarily sensitive color vision. People with tetrachromacy have four types of cones and can tell apart hundreds of millions of colors.

Tetrachromacy (from Greek tetra, meaning "four" and chroma, meaning "color") is the condition of possessing four independent channels for conveying color information, or possessing four types of cone cell in the eye. Organisms with tetrachromacy are called tetrachromats.

Tetrachromacy is a rare type of colour vision that allows people to see colours that other people can’t. Most people’s colour vision is ‘tri-chromatic’, meaning their colour vision depends on …

2023年12月21日 · Tetrachromacy is a rare eye condition that allows for increased color vision. We’ll tell you about what causes it and how it’s diagnosed, as well as why you need to be skeptical of...

2023年5月9日 · Tetrachromacy amplifies the eye’s ability to distinguish between shades of colors. This creates a visual result that some might call “super vision.” Tetrachromacy is a rare genetic phenomenon that is believed to only affect females. Up to …

2024年5月20日 · Tetrachromacy is a rare condition where an individual has four types of cone cells in their eyes, allowing them to perceive a wider range of colors. Tetrachromacy differs from normal vision in that most people have only three types of …

2014年9月5日 · Today, she knows that this is a symptom of a condition known as “tetrachromacy”. Thanks to a variation in a gene that influences the development of their retinas, people like Antico can see...

2019年12月1日 · Tetrachromatic color vision allows an individual to discriminate colors along a perceptual dimension that is unavailable to the normal person. Most people’s color perception is ‘trichromatic’, that is, their retinas contain three types of light-sensitive cone photopigment, absorbing maximally in the long-wavelength (L), middle-wavelength ...

2022年2月13日 · Tetrachromatic color vision here refers to human color vision that relies on the presence of four types of retinal cone photopigment whose signals are processed independently.

Recent years have witnessed a growing public interest in human tetrachromacy – the possibility that a subpopulation of women enjoy an extra dimension of color vision. Yet, by contrast, rigorous studies of this unusual phenotype are sparse.
