We are at the point where we need to decide on the color of out automatic cover. We are using Coverstar. We have a mid atlantic climate. My thoughts are covers are going to get dirty, so which color will show more or less dirt. Our coping is Walnut Travertine. We are leaning towards Royal or Light Blue. At this point its six one, half dozen of the other. Is one color harder to maintain appearance over the other? Or do all covers equally show dirt and wear over time? Auto cover owners, are you happy with your color choice?
