True color requires both neovim as well as a true color terminal.
I am using konsole as terminal (sudo apt install konsole).
Google for others if you don't like konsole, there are a few.
Furthermore you need to change .config/nvim/init.vim file (.vimrc if you added that to
your runtimepath); see dot_config_nvim/README-init.vim for details.
Next, install the files found in the dot_config_nvim directory
into your ~/.config/nvim directory (please also read the file
dot_config_nvim/after/syntax/cpp/README.tags.vim in this tree).
The new color scheme should now work.
If you want to change a color, edit cwcolors.vim. A handy
way to find out what is a good color for you is to compile
the colorpicker tool included in the project and use that
that to see real-time in your own .cpp file what different
colors look like. Please read ColorPicker/README for
details.
Finally, it is possible to also highlight your projects
types, classes, functions, variables etc; provided you
use ctags. Run gentags on your tags file to generate
the highlighting info for your project (normally you'd
want to do that every time you regenerate your tags file).
Please read gentags/README for further details.
