Hi, I just have a driveway done, and it has different color thy pour the concrete in winter and cover with blanquets, and I will like to know if the color going to be all the same?

Depending on where you live and how cold it was the day of the pour and every day since it was poured it may not properly set right.

As a rule of thumb on pouring concrete you don't want to pour a large area like a driveway when it is very cold out. When it is less than 40 degrees F out day and night you're asking for trouble having such a large area poured. You might have to have your driveway redone come spring/summer.
