Red is the color at the end of the visible spectrum of light, next to orange and opposite violet. Red pigment made from ochre was one of the first colors used in prehistoric art. Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to colour early pottery and later the gates and walls of palaces. Since red is the color of blood, it has historically been associated with sacrifice, danger and courage.
Modern surveys in Europe and the United States show red is also the color most commonly associated with heat, activity, passion, sexuality, anger, love and joy. In China, India and many other Asian countries it is the color of symbolizing happiness and good fortune. Pure, or solid red, the color of most ripe raspberries. Scarlet is one quarter of the way between the colors red and orange. It is the colour worn by a cardinal of the Roman Catholic Church.

Lists of shades of red and shades of pink are found at the end of this article. Bulls, like dogs and many other animals, have dichromacy, which means they cannot distinguish the color red. They charge the matador’s cape because of its motion, not its color. The human eye sees red when it looks at light with a wavelength between approximately 625 and 740 nanometers. Bulls, for instance, cannot see the red color of the cape of a bullfighter, but they are agitated by its movement. One theory for why primates developed sensitivity to red is that it allowed ripe fruit to be distinguished from unripe fruit and inedible vegetation.
This may have driven further adaptations by species taking advantage of this new ability, such as the emergence of red faces. Red light is used to help adapt night vision in low-light or night time, as the rod cells in the human eye are not sensitive to red. Today modern darkrooms usually use an amber safelight. On the color wheel long used by painters, and in traditional color theory, red is one of the three primary colors, along with blue and yellow. In modern color theory, also known as the RGB color model, red, green and blue are additive primary colors. Red, green and blue light combined together makes white light, and these three colors, combined in different mixtures, can produce nearly any other color.
So that the maximum number of colors can be accurately reproduced on your computer screen, each color has been given a code number, or sRGB, which tells your computer the intensity of the red, green and blue components of that color. The intensity of each component is measured on a scale of zero to 255, which means the complete list includes 16,777,216 distinct colors and shades. In a traditional color wheel from 1708, red, yellow and blue are primary colors. Red and yellow make orange, red and blue make violet. In modern color theory, red, green and blue are the additive primary colors, and together they make white.
A combination of red, green and blue light in varying proportions makes all the colors on your computer screen and television screen. Sunsets and sunrises are often red because of an optical effect called Rayleigh scattering. As a ray of white sunlight travels through the atmosphere to the eye, some of the colors are scattered out of the beam by air molecules and airborne particles due to Rayleigh scattering, changing the final color of the beam that is seen. Lasers emitting in the red region of the spectrum have been available since the invention of the ruby laser in 1960. Mars is called the Red Planet because of the reddish color imparted to its surface by the abundant iron oxide present there. Jupiter’s surface displays a Great Red Spot caused by an oval-shaped mega storm south of the planet’s equator.
