Colors table about vim-gruvbox8

[lifepillar]

You may find the colors in the files in the templates folder. For instance, start with gruvbox8.colortemplate, then check the included files. Each line starting with Color: defines a color: name, GUI value, 256-color number, and 16-color value.

If you feel like formatting those into a table to put it in the Readme, I will gladly accept a pull request :-)

Yeah, I thought there might be a similar table to gruvbox-contrib. :D
But running grep against templates did the trick. So, the main changes were to 256-color numbers (and I must say I like the new values better).
