I mostly have the old green cutting mats....too many to replace....but I also picked up one at a local chain store that has yellow on one side and a light green on the other side....so if I have a fabric that is hard to see, I just change out the cutting mat. No matter what color mat you have, there will always be a fabric that is hard to see on it....so having a choice of colors works for me. I seldom measure using the markings on the mat....just use the lines to line up the straight edge of the fabric with.
