Yellow is the colour between orange and green on the spectrum of visible light. It is evoked by light with a dominant wavelength of roughly 570–590 nm. It is a primary colour in subtractive colour systems, used in painting or colour printing. In the RGB colour model, used to create colours on television and computer screens, yellow is a secondary colour made by combining red and green at equal intensity. Carotenoids give the characteristic yellow colour to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage. Sunlight has a slight yellowish hue when sun is near a horizon, due to atmosphere scattering shorter wavelengths (green, blue, and violet).

Because it was widely available, yellow ochre pigment was one of the first colours used in art; the Lascaux cave in France has a painting of a yellow horse 17,000 years old. Ochre and orpiment pigments were used to represent gold and skin colour in Egyptian tombs, then in the murals in Roman villas. In the early Christian church, yellow was the colour associated with the Pope and the golden keys of the Kingdom, but was also associated with Judas Iscariot and was used to mark heretics. In the 20th century, Jews in Nazi-occupied Europe were forced to wear a yellow star. In China, bright yellow was the colour of the Middle Kingdom, and could be worn only by the Emperor and his household; special guests were welcomed on a yellow carpet.

According to surveys in Europe, Canada, and the United States, yellow is the colour people most often associate with amusement, gentleness, humour, and spontaneity, but also with duplicity, envy, jealousy, avarice, and, in the U.S., with 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 colour of happiness, glory, harmony and wisdom.
