We’ve had this on our deck for about a month now. The color is a nice medium gray and it actually dries out pretty quickly after it rains. 
Very sturdy outdoor material. Only 2 minor inconveniences

1. The textured design makes it hard to sweep off leaves 
2. On windy days it’s not heavy enough to avoid the corners flapping over. Plan to apply some rug tape on the corners where furniture isn’t holding it down.
