Need Advice - Stains in recent patio pour

I really need someones advice, I just recently had a pour done and it was a rainy day, my gutter was dripping onto the fresh pour and the concrete company put a rubber mat where the drip was and told me to leave it there until the next day. The area seems as if it never fully cured where the rubber mat was and even has water drip stains. It has been about a month since the pour and I am hoping with sun this will cure to look like the rest of the patio, but any advice would be greatly appreciated. Here is a picture of the stain:

Actually, your photo indicates that the concrete under the rubber mat cured more fully and rapidly than that around it, simply because the mat held moisture in that is needed for the Portland cement in the mix to hydrate properly, instead of evaporating off where uncovered.

Over time, the differences in color will neutralize, and in a few months it will be hard to see where the mat was.
