I bought two of these in a round shape.  They sit under two smaller 3 person tables on the pool patio.  These rugs have kept their color and do not look dirty at all.  I have had them for 7 months and they still look great.  The colors blend in nicely with the outdoor plants and foliage.  Quality is nice.  They feel like an indoor rug.  It is not the plasticky feel like some.  Very nice.
