Pure yellow light is composed of equal amount of red and green light. The color box at right shows the most intense yellow representable in 8-bit RGB color model; yellow is a secondary color in an additive RGB space. This color is also called color wheel yellow.
Yellow is the color of light with wavelengths predominantly in the range of roughly 570–580 nm. In the HSV color space, it has a hue of around 60°. It is considered one of the subtractive primary colors .
It is evoked by light with a dominant wavelength of roughly 575–585 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.
Typically there are two different types of color charts: Color reference charts are intended for color comparisons and measurements. Typical tasks for such charts are checking the color reproduction of an imaging system, aiding in color management or visually determining the hue of color.

Note that the Munsell Book of Color contains more color samples than this chart for both 5PB and 5Y (particularly bright yellows, up to 5Y 8.5/14). However, they are not reproducible in the sRGB color space , which has a limited color gamut designed to match that of televisions and computer displays.
The result is that red light is bent less sharply than violet as it passes through the prism, creating a spectrum of colors. Newton's observation of prismatic colors (David Brewster 1855) Newton originally divided the spectrum into six named colors: red, orange, yellow, green, blue, and violet.
The typical artists' paint or pigment color wheel includes the blue, red, and yellow primary colors. The corresponding secondary colors are green, orange, and violet or purple. The tertiary colors are green-yellow, yellow-orange, orange-red, red-violet/purple, purple/violet-blue and blue-green.
