The shutters read brown on my monitor, but it could be the light in the photo, which I think it probably really oranging the brick, too? If you wanted to leave the shutters as is, I might try a teal or turquoise door, but I happen to love that color with brick. I picked this photo when I thought your shutters were brown. I found this of the garage doors painted the same color as the siding (although different color than yours) and like how it looks with no trim. I also think this is a great color with the brick, but probably not with your siding (unless you'll be painting that, too). I like the darker trim color with it all. This is from an older GW thread, so I hope the OP doesn't mind GW thread

This is a recommended color from SW for Mindful Gray…homburg gray. I would do this on the shutters and the garage doors and leave the wood door as is. The two middle windows shouldn’t have shutters as the won’t fit appropriately, but you are not painting the siding and the darker outlines of the shutters will show if you don’t replace what was there. Personally, would like the house with out shutters and would probably paint the siding and garage doors and have no shutters at all.

I like a green-blue suggestion above, but your exterior colors are so neutral that you can choose almost any color you like and it will be another step to make this house "yours". A bright blue door will make a bold statement and will be an eye-catching focal point distracting from poor landscaping. On the porch, you can add an outdoor chair and decorate it with some bright pillows that will match your front door. If there is not enough space for chair you can add an unusually patterned rug. Read more about how to choose a color for the front door and how to paint it properly. On both sides of the stairs, you can add pots of flowers it is a good idea to make your entry more inviting and interesting. Some inspirational pictures:

An entry door needs much more than an actually visible color. It needs the approach to it to have clues that it exists, and that people are welcome to come to that door. There doesn’t seem to be much of an encouraging wide and friendly pedestrian path to the porch, where presumably, people will travel. Right now? This looks like the cars are telling people that they are not welcome. The garage is the most obviously important part of the facade. It’s the most obvious and prominent element. And the front door isn’t visible, and has no designed path of destination to it. The hardscape and landscape design needs to overcome this. Paint is secondary. But yes, paint all of the batten trim and the garage doors the house body color. That body color may need a big workout on a lot of elements, actually. Every necklace in the jewelry box is being used, and it’s too much. The entry door needs a light bright color. School bus yellow. Bubble gum pink. Orchid purple. Acid citron green. Something that shouts rather than hides behind its mother’s apron.
