Question

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

I believe you have 'cursorline' set. The CursorLine highlight group defines the highlights for the same. Either you set nocursorline, (which can speed line movements) or change the CursorLine highlight groups fg colors.
