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.^[1]
