Has anyone heard of the Colors of Advent devotional?

I am living in Sweden now and the last year I was at my previous church, they introduced a new Advent ceremony using different colors other than the traditonal purple/pink/white. The only thing I remember clearly is that the center candle was red for Christ's blood shed on the cross. Has anyone heard of this, can you give me the other colors or maybe even a web link? I would like to use it in my home this year and yes, I do know it is only July, but we are having a christmas dinner for my sister-in-.law and it started me thinking.....
