I could see on the teal Olfa mat pretty well, except for similar colors and black. I now use the Martelli, and flip the mat to purple when cutting mostly light fabrics, and to the yellow for cutting darker. The main concern for me in a mat is the finish. I like something that is a bit grippy, which the Olfa and Martelli are, but I found the Quilter's Select to be too slippery for me.
