Yellow

Yellow is the color between green and orange on the spectrum of visible light. It is evoked by light with a dominant wavelength of roughly 570590 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, and daffodils, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage. Sunlight has a slight yellowish hue, due to the surface temperature of the sun.

Yellow is the easiest color to spot at a distance. That's why most taxis in New York are yellow!
