This mat is thick and so far stays in place on our tile floor.  The color is the same as it appeared on my monitor.  The only drawback is a musty smell, which also permeated the packing box.  It's probably not a manufacturing defect, since other reviews mentioned that there was no chemical or other odor.  Perhaps it resulted from long-term storage in a damp warehouse?  At this time it's sitting outside on our back patio, with a goal of airing out.  It's slow going due to the short, grey, cold days of winter.  Some bright sun for a long day or two would probably take care of it.   Would very much like to use it indoors, and hope it freshens up soon.
