Spring green is a color that was traditionally considered to be on the yellow side of green, but in modern computer systems based on the RGB color model is halfway between cyan and green on the color wheel.
The modern spring green, when plotted on the CIE chromaticity diagram, corresponds to a visual stimulus of about 505 nanometers on the visible spectrum. In HSV color space, the expression of which is known as the RGB color wheel, spring green has a hue of 150°. Spring green is one of the tertiary colors on the RGB color wheel, where it is the complementary color of rose.
The first recorded use of spring green as a color name in English was in 1766, referring to roughly the color now called spring bud.

Seattle is sometimes referred to as the Emerald City, because its abundant rainfall creates lush vegetation.

Other variations of spring green
Green (CMYK) (pigment green)
The color defined as green in the CMYK color system used in printing, also known as pigment green, is the tone of green that is achieved by mixing process (printer's) cyan and process (printer's) yellow in equal proportions. It is displayed at adjacent.
left|thumb|[[Cyan, magenta, and yellow are the three subtractive primary colors used in printing.]]
The purpose of the CMYK color system is to provide the maximum possible gamut of color reproducible in printing.
The color indicated is only approximate as the colors of printing inks may vary.
Green (NCS) (psychological primary green)
The color defined as green in the NCS or Natural Color System is shown at adjacent (NCS 2060-G). The natural color system is a color system based on the four unique hues or psychological primary colors red, yellow, green, and blue. The NCS is based on the opponent process theory of vision.

Green (Munsell)
The Munsell color system is a color space that specifies colors based on three color dimensions: hue, value (lightness), and chroma (colorfulness), spaced uniformly (in terms of human perception) in three dimensions in the Munsell color solid. In order for all the colors to be spaced uniformly, it was found necessary to use a color wheel with five, non-arbitrary, equally spaced primary colors: red, yellow, green, blue, and purple.
The color of the sample is the most chromatic (colorful) green in the sRGB gamut that falls in the hue of 5G (primary green) in the Munsell color space.
Green (Pantone)
Hooker's green is a dark green color created by mixing Prussian blue and gamboge. It is displayed adjacent. Hooker's green takes its name from botanical artist William Hooker (1779–1832) who first created it particularly for illustrating leaves.
