Vertical split is ugly

[lewisthompson]

Really liking this theme but unfortunately I can't get past the all white with a thin black line vertical window split. Would it be possible to invert this so we have a thin white line instead?

Perhaps something like hi VertSplit guibg=white guifg=black except using your defined colors?
