According to surveys in Europe, Canada, the United States and elsewhere, yellow is the color people most often associate with amusement, gentleness, humor, happiness, and spontaneity, but also with duplicity, envy, jealousy, greed, and, in the U.S., cowardice. In Iran it has connotations of pallor/sickness, but also wisdom and connection. In China and many Asian countries, it is seen as the color of happiness, glory, harmony and wisdom.

Process yellow is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure yellow ink.
The yellow on a color television or computer screen is created in a completely different way; by combining green and red light at the right level of intensity. (See RGB color model).
Complementary colors
Traditionally, the complementary color of yellow is purple; the two colors are opposite each other on the color wheel long used by painters.

Vincent Willem van Gogh (; 30 March 185329 July 1890) was a Dutch Post-Impressionist painter who posthumously became one of the most famous and influential figures in Western art history. In a decade, he created about 2,100 artworks, inc ...
, an avid student of color theory, used combinations of yellow and purple in several of his paintings for the maximum contrast and harmony.
Hunt defines that "two colors are complementary when it is possible to reproduce the tristimulus values of a specified achromatic stimulus by an additive mixture of these two stimuli." That is, when two colored lights can be mixed to match a specified white (achromatic, non-colored) light, the colors of those two lights are complementary. This definition, however, does not constrain what version of white will be specified. In the nineteenth century, the scientists

and Helmholtz did experiments in which they concluded that finding a good complement for spectral yellow was difficult, but that the result was indigo, that is, a wavelength that today's color scientists would call violet or purple. Helmholtz says "Yellow and indigo blue" are complements. Grassmann reconstructs Newton's category boundaries in terms of wavelengths and says "This indigo therefore falls within the limits of color between which, according to Helmholtz, the complementary colors of yellow lie."
Newton's own color circle has yellow directly opposite the boundary between indigo and violet. These results, that the complement of yellow is a wavelength shorter than 450 nm, are derivable from the modern CIE 1931 system of colorimetry if it is assumed that the yellow is about 580 nm or shorter wavelength, and the specified white is the color of a blackbody radiator of temperature 2800 K or lower (that is, the white of an ordinary incandescent light bulb). More typically, with a daylight-colored or around 5000 to 6000 K white, the complement of yellow will be in the blue wavelength range, which is the standard modern answer for the complement of yellow.

s emitting in the yellow part of the spectrum are less common and more expensive than most other colors. In commercial products diode pumped solid state ( DPSS) technology is employed to create the yellow light. An infrared laser diode at 808 nm is used to pump a crystal of neodymium-doped yttrium vanadium oxide (Nd:YVO4) or neodymium-doped yttrium aluminum garnet (Nd:YAG) and induces it to emit at two frequencies (281.76 THz and 223.39 THz: 1064 nm and 1342 nm wavelengths) simultaneously. This deeper infrared light is then passed through another crystal containing potassium, titanium and phosphorus (KTP), whose non-linear properties generate light at a frequency that is the sum of the two incident beams (505.15 THz); in this case corresponding to the wavelength of 593.5 nm ("yellow"). This wavelength is also available, though even more rarely, from a

The Dutch modernist painter Piet Mondrian made a series of paintings which consisted of a pure white canvas with a grid of vertical and horizontal black lines and rectangles of yellow, red, and blue.

to yellow, depending upon the type of saffron and the process. Most saffron today comes from Iran, but it is also grown commercially in Spain, Italy and Kashmir in India, and as a boutique crop in New Zealand, the United Kingdom, France, Switzerland and other countries. In the United States, it has been cultivated by the Pennsylvania Dutch community since the early 18th century. Because of the high price of saffron, other similar dyes and spices are often sold under the name saffron; for instance, what is called ''Indian saffron'' is often really turmeric.
* Reseda luteola, also known as dyers weed, yellow weed or weld, has been used as a yellow dye from neolithic times. It grew wild along the roads and walls of Europe, and was introduced into North America, where it grows as a weed. It was used as both as a yellow dye, whose color was deep and lasting, and to dye fabric green, first by dyeing it blue with indigo, then dyeing it with reseda luteola to turn it a rich, solid and lasting green. It was the most common yellow dye in Europe from the Middle Ages until the 18th century, when it was replaced first by the bark of the quercitron tree from North America, then by synthetic dyes. It was also widely used in North Africa and in the Ottoman Empire.

Symbolism and associations
In the west, yellow is not a well-loved color; in a 2000 survey, only six percent of respondents in Europe and America named it as their favorite color. compared with 45 percent for blue, 15 percent for green, 12 percent for red, and 10 percent for black. For seven percent of respondents, it was their least favorite color.Eva Heller (2000), ''Psychologie de la couleur – effets et symboliques'', p. 33. Yellow is the color of ambivalence and contradiction; the color associated with optimism and amusement; but also with betrayal, duplicity, and jealousy. But in China and other parts of Asia, yellow is a color of virtue and nobility.
In China
Yellow has strong historical and cultural associations in China, where it is the color of happiness, glory, and wisdom. In China, there are five directions of the compass; north, south, east, west, and the middle, each with a symbolic color. Yellow signifies the middle. China is called the Middle Kingdom; the palace of the Emperor was considered to be in the exact center of the world.Eva Heller (2000), ''Psychologie de la couleur – effets et symboliques'', p. 82.

Light and reason
Yellow, as the color of sunlight when sun is near the horizon, is commonly associated with warmth. Yellow combined with red symbolized heat and energy. A room painted yellow feels warmer than a room painted white, and a lamp with yellow light seems more natural than a lamp with white light.
As the color of light, yellow is also associated with knowledge and wisdom. In English and many other languages, "brilliant" and "bright" mean intelligent. In Islam, the yellow color of gold symbolizes wisdom. In medieval European symbolism, red symbolized passion, blue symbolized the spiritual, and yellow symbolized reason. In many European universities, yellow gowns and caps are worn by members of the faculty of physical and natural sciences, as yellow is the color of reason and research.
Gold and blond
In ancient Greece and Rome, the gods were often depicted with yellow, or blonde hair, which was described in literature as 'golden'. The color yellow was associated with the sun gods Helios and
. It was fashionable in ancient Greece for men and women to dye their hair yellow, or to spend time in the sun to bleach it.Eva Heller (2000), ''Psychologie de la couleur – effets et symboliques'', p. 73. In ancient Rome, prostitutes were required to bleach their hair, to be easily identified, but it also became a fashionable hair color for aristocratic women, influenced by the exotic blonde hair of many of the newly conquered slaves from Gaul, Britain, and Germany. However, in medieval Europe and later, the word yellow often had negative connotations; associated with betrayal, so yellow hair was more poetically called 'blond,' 'light', 'fair,' or most often "golden".
Visibility and caution
Yellow is the most visible color from a distance, so it is often used for objects that need to be seen, such as fire engines, road maintenance equipment, school buses and taxicabs. It is also often used for warning signs, since yellow traditionally signals caution, rather than danger. Safety yellow is often used for safety and accident prevention information. A yellow light on a traffic signal means slow down, but not stop. The Occupational Safety and Health Administration (OSHA) uses Pantone 116 (a yellow hue) as their standard color implying "general warning", while the Federal Highway Administration similarly uses yellow to communicate warning or caution on highway signage. A yellow penalty card in a soccer match means warning, but not expulsion.
