Color blindness is most commonly an inherited condition that limits people's ability to perceive differences in color, or, more rarely, see certain colors at all.
In simplest terms, those of us without color blindness can observe all the wavelengths of light that exist in the universe, which our brains then perceive as color. Our eyes have all three types of cones: long, medium, and short — each of which is sensitive to a different part of the visible spectrum (red, green, and blue, respectively).
Photographer Davide Sasso has created a series that explores the way people with Tritanopia, or blue-yellow color blindness, may possibly see the world. Tritanopia is an extremely rare condition in which people lack blue cone cells in their eyes. As a result, blues appear greenish; yellow and oranges appear violet, pinkish, or light gray; and purples appear dark red.
As Rafi Letzer previously wrote, it's difficult for people with color blindness, himself included, to demonstrate their objective perception of colors in the world. But tools online, such as this color blindness simulator by Colblindor, and projects like Sasso's may help give us some insight.
Below, take a closer look at Sasso's stunning project.
Here is how a person without color blindness may see a forest floor covered in fall foliage.
Here is a photo Sasso edited to show how a person with blue-yellow color blindness may see the same photo of a forest floor. The bright green of the leaf in the middle is much more muted, and the yellows and oranges take on deep pink and gray tones.
Here is another example of how someone with blue-yellow color blindness may see a forest during the fall.
