I just had my hail roof reshingled. Drove around the area to see what people have done. It seems like every house got hit within 2 miles. My prior roof was a black mix and a lot of houses have chosen the same. Not sure if this was to insulate with the sun during winter on black or just a choice. My decision ended up with mixed shades of gray and like it so much better. Mainly because the roof looks like shingles. I have a white cottage, am not suggesting this color for yours. What is directing you thoughts towards a black mix? If there are other homes in your area similar, suggest a drive to see what they look like.

I think you could probably leave garage door as it is, but darken the trim around the door, the pergola, etc. I can’t clearly tell what color your garage door is to be able to say what trim color would work the best. If you wanted more of a look that would showcase the garage, I would say a wood door. Or a red door.

There is a large camp of no shutter people on Houzz. If they don't function or are not as large as they should be to function - get rid of them. I sometimes agree, and sometimes feel like the shutters add color and interest and are there purely for decorative reason, and this is perfectly okay. Your description of Victorian Inspired is also fine. It is not a Gothic (Think Haunted House) or Queen Anne Victorian, but it has the general shape and feel of a Victorian home, which is why you used the word "inspired." "Queen Anne homes are the quintessential Victorian home: They are asymmetrical, two or three (or more) stories tall, have steeply pitched roofs and large wrap-around porches. They are often adorned with differing wall textures and ornate trim—which gives them the “gingerbread” effect commonly associated with Victorian homes—that is typically painted in a variety of accent colors. Some Queen Anne homes also have octagonal towers (topped with a round pointed roof) and ornate bay windows—in short, nothing about these homes is subtle." Not all Victorians are the quintessential Victorian. Here is one that was featured in Architectural Digest. If all you want to do is change the color of the shutters, door and garage door and you found something that you think is beautiful a few blocks away, I would go knock on their door and ask what colors they used. My experience is that people are truly flattered when you knock on their door and ask something about their color choices or landscape choices. I have ended up in long conversations and even been given home and garden tours by doing this. I have gotten plant cuttings and been given samples of paint when the label was unreadable. I have never been turned away or scolded for admiring someone's home.

You don't want to hear it, but you need to paint the garage doors the same color as the body of the house. That dark brown door is dominating whatever decision you make. It looms over everything else. Find a color that is close to the color of the brick. Paint everything with that color, including the garage door. Of the three colors illustrated, I like the top color. It's pretty close to the brick color. When you change the front door out, you can paint or stain it another color. Use as few colors as possible. This is not a painted lady Victorian. Three colors are the maximum and the brick counts as a color.
