Garrett Morgan’s Traffic Signal Legacy . Garrett Morgan invented the traffic signal, but one key scientific point that got completely missed was that red-green is the most common form of color blindness in humans. Almost 8% of men are color blind due to hereditary reasons, specifically because of something called X-Linked Recessive Inheritance. That means 322 million people today struggle with distinguishing red from green. This type of color blindness is called Deuteranomaly. Now, Morgan patented a three-position traffic signal (Stop, Go, and an "all-directional stop" for pedestrians), but he didn’t actually create the red-green color system—that was already in use. But if whoever came up with the red-green combo had considered human hereditary data, we’d probably be using a different set of colors for traffic lights today. On the flip side, if you ever take the route from Hosur to Chennai, you might notice some traffic lights using blue and white instead of red and green. I couldn’t find solid info on why this exists, but most locals say it’s to help drivers better visualize traffic flow on highways. Pun* So, the next time you see a man jumping a signal and have a thought, "Andhaa he kya BKL", may be he is !! Activate to view larger image,

Color isn’t just about wavelength; context plays a crucial role too. For instance, an image of strawberries might appear red to us even if there are no red pixels. Our brains perform color correction based on lighting and familiar colors. This phenom
