In my terminals I use #7fff7f for green and #daa520 (X11 color "goldenrod") for amber. The matches, to me, are pretty close (my brain's reference for the green is a TRS-80 Model 16 with the brightness up).
Does golden rod mean something other than what it sounds like? A tube of gold? What is colourwise peculiar about a golden rod?
"Goldenrod is a common name for many species of flowering plants in the sunflower family" - https://en.wikipedia.org/wiki/Goldenrod
Although the picture there looks more yellow than amber.
Added as an X11 color name in 1989, replacing the name "OldGoldenrod". https://cgit.freedesktop.org/~alanc/xc-historical/commit/xc/... .
