Red is an irritating color to the human brain. Red grabs our attention, which is why stop signs, red lights and sports cars all are bathed in it. Irritating doesn’t always mean a bad thing. In reference to gun sights, red is quick for the eye to pick up, for the brain to process and contrasts against almost every background, which makes it easy to distinguish red hues in the visible spectrum.
Besides fiber optic sights, red is almost exclusively used in miniature reflex sights as the dot reticle. It’s so common, in fact, that “red dot sights” has become the collective label for this optic category. Compared to other colors, red LED emitters have been all but perfected, as they now require less energy to run for longer durations between battery changes. Red dots have proven to be very durable and resistant to the stress of recoil impulses generated and transferred after a gun is fired.
The color red isn’t without drawbacks, however. A red dot can appear harsh to some eyes, and tends to bloom and create aberrations or flares as the intensity is cranked up. Like staring into a bright light, some human eyes don’t perceive or are not as sensitive to the color red.
