Hello :)
Welcome to my page 👋🏾
While searching for a username I stumbled onto a page with all types of colours, who knew there could be that many shades of green? (https://www.color-meanings.com/shades-of-green-color-names-html-hex-rgb-codes/)
After searching Wikipedia I had to realize that swamp-green sadly seems to be missing from the list of different shades of green (https://en.wikipedia.org/wiki/Shades_of_green).
