That's true after fiddling around. It seems whatever Player is int he "next" state will show the 'see through', where as everything else will show the specified colour.
At the moment i now have
NextRowColor=#000000
LoadedRowColor=#000000
LoadedColor=#000000
But still, the "next" state player shows the default colour.
Thanks.
EDIT- Nevermind, found out it was "NextColor=#000000" which needed to be added! Thanks Torben.
