In this Vim screenshot you can see that when moving the cursor over a line it changes the normal color of the whitespace characters (shown on the left) from grey to black. Can I stop this and leave them showing grey always, regardless of cursor position?
I've tried setting these in the colour scheme but no luck:
hi SpecialKey guibg=bg guifg=#CCCCCC gui=none
hi NonText guibg=bg guifg=#CCCCCC gui=none
