A gray/green could be nice with your brick. These are all from Ben Moore.

@Allison0704 - it is beyond exciting to see progress. I was also surprised at how huge the house looks, even though the first floor is around 1800 sq ft. @ptreckel - thanks for noticing! that detail! I am really happy with what the designer came up with :)

Is the door in good shape outside of the finish issue? If so, have you had a professional take a crack at refinishing? If that is off the table, I'd agree with the above, Provia, HMI, and HomeGuard make very nice entry doors in fiberglass or steel. The latter two are someowhat regionally available. A factory applied finish being baked enamel if painted, or automotive grade clear coat over stain will do the trick in terms of standing up to the elements. Color-wise, I think that the pics above showing either stain that matches your garage door or paint that matches the windows are probably the two obvious choices. My vote would be to match the garage door unless you plan to change that.

We will have a traditional lockset on the door. My mindset is people who want to get in - WILL.  They likely wouldn't even take the front door and  I have (4) large sliders along the back and side of the house. Perfect for breaking in, or even our backdoor to enter the garage. I am not concerned about the glass door being secure.   I don't have curtains /or blinds on most windows.  The bedroom windows in the front of the home are the only place. The back and sides of the house have no coverings. I am all about open windows lol. It used to drive him bananas. He has accepted it now.  I live in a rural area, 300+ft long driveway and no  homes that can see us. Woods on all sides.  My husband doesn't think the glass door looks classless or anything like that. He just wanted to a more traditional wood door. I just REALLY want to have glass to let the light in. That area is the darkest spot in the house because of the farmers porch overhang. It blocks the sun/light and shades the 1st floor front of the house.
