For some people with severe allergies, exposure to their allergen can result in a life-threatening reaction called anaphylaxis. Anaphylaxis is a severe allergic reaction to venom, food, or medication. Most cases are caused by a bee sting or eating foods that are known to cause allergies, such as peanuts or tree nuts. Anaphylaxis causes a series of symptoms, including a rash, low pulse, and shock, which is known as anaphylactic shock.

In the RGB color model, the light of two complementary colors, such as red and cyan, combined at full intensity, will make white light, since two complementary colors contain light with the full range of the spectrum.
