I was down at the Home Depot in the flooring section and to my surprise there is a tile grout color named "Delorean Gray" It should be called "Dirty Delorean Gray" in my opinion but, at least they tried! I wonder if someone at the supplier (Custom Building Products) is a Delorean fan or owner? Here is a link to the color samples (see #165 Delorean Gray) http://www.custombuildingproducts.com/installation/Groutcolors.htm Mauri. #3153 Austin, TX
