Just wondering if there is a general rule of thumb when picking out exterior colors. Should the trim around the windows, garage doors and storm door all match? Also, I will have a storm door in front of my entry door. Should they both be the same color( Mesa red) or should the storm door match the trim on my windows and can the garage doors be chocolate brown if the trim around the windows is taupe? The siding is mountain sage. Soooooo many decisions! Please help. Thank you in advance.
