You are naming or implying things which remind me of or are the color green, but no one knows how green is actually perceived by anyone else, but through the experiences we have had with similar circumstances, we are reminded of what we have seen, which may not be what someone else has.
Yes it is all the same group of color, but that is likely because it is a similar group of photon wavelengths and combinations. Although we have cleverly thought up color schemes which have sharp switches in color for representing important data graphically (see Dvorak infrared imagery), but since when did anything natural have such high contrast? For example, put a parcel of air 800 hPa next to one that's 1100 hPa with no gradient. That doesn't happen. Nor does 988 next to 990.
