viewhue.
view hueoffers an experience of how the world appears to individuals with various forms of color vision deficiency.
This interactive application simulates different types and degrees of color blindness, from protanopia to deuteranopia and tritanopia, among others, creating awareness and empathy for the way approximately 8% of the global population perceives color.
concept.
view hue was inspired by the recognition that most people with normal color vision rarely consider how differently others might perceive the world. the project aims to bridge this experiential gap by creating an interactive simulation that transforms any visual input—whether from a camera feed or uploaded images—to accurately represent various forms of color vision deficiency.
by applying scientifically accurate algorithms that model how photoreceptors in the human eye respond differently in color vision deficiency, view hue creates a profound empathy tool. it serves both educational purposes and as a practical utility for designers to create more accessible visual content by experiencing their work through the eyes of diverse viewers.
what is color blindness?
color blindness, also known as color vision deficiency, happens when a person cannot see colors in the usual way due to issues with the light-sensitive cells (cones) in the eye. these cones are responsible for detecting red, green, and blue light.
depending on how the cones function, there are several types of color blindness.
types of color blindness.
this occurs when one type of cone is either missing or doesn't work properly. the main types include:
protanopia.
red cones (L-cones) are missing or nonfunctional. this affects the perception of reds and makes greens appear more muted.
deuteranopia.
green cones (M-cones) are missing or nonfunctional. this affects green tones, causing confusion between reds and greens.
tritanopia.
blue cones (S-cones) are missing or nonfunctional. this results in difficulties distinguishing blues from yellows. It is less common than the others.
other variations.
dual cone deficiency.
when two types of cones are impaired. the individual’s perception is limited almost entirely to shades of a single tone: red, green or blue.
achromatopsia.
if all three cones are nonfunctional, this leads to achromatopsia (complete color blindness), where the world appears only in grayscale.
tetrachromacy - an interesting valiration.
though not a deficiency, there's also tetrachromacy, a rare condition where a person has four types of cones instead of three. this allows them to see a broader range of colors and nuances than most people. it's believed to occur more commonly in women.
