Cyanophobia (from the Greek word kyanos, meaning "dark blue", and phobos, "fear") is the fear of the color blue. Cyanophobic sufferers may panic often because it is difficult for sufferers to avoid encountering that color since blue is commonly seen on everyday objects, although blue is rarely seen in nature apart from the sky and bodies of water. Cyanophobic sufferers would not own anything blue, like jeans. Extreme sufferers may panic so violently that it would draw blood. To avoid panic, sufferers may recommend wearing red- or orange-tinted glasses. Sufferers would not eat blueberries or other blue foods. It is caused by dangerous events relating to the color. Windows users may also have this phobia due to the Blue Screen Of Death.
