As far as I know the ususal color of the Lille home kit is red. This season home kit is white because of the 70th anniversary of the club and was inspired by the first ever Lille jersey. So I think both colors are possible to use for the home kit :-)
Well as far as I have seen in their club history on their web site they have mostly used white but from 1998 they started to use red for their home kit so I presume both can be used as a home kit color. http://www.losc.fr/club-lille/histoire?periode=8#view-filters But Gaabowski I was not criticizing you for using red I just wondered if I had misunderstood something.
