There are three main types of color vision deficiency: red-green, blue-yellow, and complete. Color blindness, or color vision deficiency, affects the way you perceive color and can make it hard to ...

After decades of studying color vision in mice, new research in zebrafish has allowed experts to uncover how some animals regulate their ability to see blue light. The results allow researchers to ...

A new experiment into color vision has allowed a select group of human subjects to see a new color. Subjects describe the “unprecedented” color as a very saturated teal. Researchers are looking into ...
