Spring bud
Spring bud is the color that used to be called spring green before the X11 web color spring green was formulated in 1987 when the X11 colors were first promulgated.  This color is now called spring bud to avoid confusion with the web color.

The color is also called soft spring green, spring green (traditional), or spring green (M&P).

The first recorded use of spring green as a color name in English (meaning the color that is now called spring bud) was in 1766.
