This is the actual color of the “charcoal” shed 
Picture looks almost black and what I got is light grey, definitely not charcoal !! Disappointed 
Building it isn’t the easiest but if you follow the picture it isn’t bad, quality is not good, very flimsy not sturdy, my husband had to install wood studs inside this shed so it felt properly strong to withstand any type of wind or storm!  WOULD NOT RECOMMEND
