Similar to the way sound waves of different wavelengths give higher- or lower-pitched sounds, different wavelengths of light are perceived as different colors (4).
Knowing how light behaves helps us understand the concept of color and how we see it. People with protanomaly (B) and deuteranomaly (C) - two types of color blindness-may have difficulty noticing details in their surroundings. Without color vision, humans lose a significant amount of critical information.įigure 1 ~ Color vision allows humans to more easily detect borders of objects (A). 1) (3), picking up on non-verbal social signals, and noticing details about the environment (2). Color vision is particularly important in detecting the borders of objects (Figure. Among our other senses, hearing provides just 5% and our other senses provide even less (2). Vision is the most important sense for humans, providing 90% of the information we process.

Fortunately, new technology is allowing people with a common type of colorblindness to see the world in full color for the first time. Thus, although they might be able to tell you what color the dress is, other colors may be impossible for them to distinguish. Colorblind people are unable to distinguish certain shades of color, depending on the type of colorblindness. Colorblindness, on the other hand, is caused by differences in our eyes, not our brains. As it turns out, however, the dress is simply a type of optical illusion-a difference in how our brains process visual information, not a problem with anyone’s eyes. Some of you may even have worried that you were colorblind when you saw a different color dress than your peers.
You probably also formed a firm opinion about whether the dress was blue and black or white and gold. You probably saw the photo of the dress that caused an uproar on the Internet a few weeks ago (1).
