What Color Should You Paint a Front Door on a Gray Brick House?
A homeowner on r/ExteriorDesign posted their 1940s Cape Cod and asked the internet one of the most common curb appeal questions: what color would you paint the front door?
45 comments later, the thread had everything from saffron yellow to eggplant. Jewel tones dominated. But nobody could actually show what any of these would look like on this specific house.
So we did.
The Starting Point
Gray brick facade. Dark charcoal shutters. White trim. Slate roof. Mature trees. The bones are solid. The current door is a faded mint green that disappears into the background. It's not bad. It's just not doing anything.
The shutters are already doing the heavy lifting with that dark charcoal. The door just needs to join the conversation.
Navy Blue. The Safe Bet That Isn't Boring.
What we told RAI:
"Deep navy blue front door. Keep the brick, shutters, white trim, and roof."

Navy against gray brick is one of those combinations that just works. It reads as intentional without screaming for attention. The white trim frames it. The dark shutters echo it without matching it exactly.
If you're the type who wants the door to feel considered but not loud, this is the move. Benjamin Moore Hale Navy is in this family.
Why it works: Navy sits between the charcoal shutters and the white trim. It adds depth to the palette without introducing a new temperature.
Burgundy. Reddit's Pick. They Were Right.
What we told RAI:
"Deep burgundy wine red front door. Keep everything else identical."

This was the most upvoted suggestion in the thread, and seeing it on the actual house confirms the instinct. The warm red against cool gray brick creates the kind of contrast that makes you slow down on a walk.
It pulls from a totally different color family than anything else on the facade. That's the point. The door becomes the focal point instead of blending in.
Why it works: Warm jewel tones against cool neutrals create visual tension. The burgundy doesn't match anything. It leads.
Matte Black. The Bold Move.
What we told RAI:
"Matte black front door. Keep all other elements identical."

Black unifies. The shutters are already dark charcoal. A matte black door ties them together and turns the whole facade into a coordinated statement. It skews modern on a traditional house, which is exactly the tension that makes it interesting.
This is the least safe choice here and also the most photogenic one.
Why it works: Black anchors the eye and creates a visual grouping with the shutters. The white trim pops harder. The brick reads warmer by contrast.
Which One Should You Pick?
It depends on what you want the house to say.
Navy if you want sophisticated and timeless. Works with brass hardware and lantern-style porch lights. The most "magazine" of the three.
Burgundy if you want warmth and personality. Works with black iron hardware. The most inviting of the three. Reddit agreed, and they were right.
Matte black if you want bold and modern. Works with matte black hardware (obviously). The most dramatic of the three. Pairs well with a statement house number.
All three work with this brick. None of them are wrong. The current faded mint, though. That one's wrong.
How We Made These
We opened the original photo in Renovate AI and told RAI to change just the front door color. One direction at a time. Each design came back in about 30 seconds.
The trick with exterior work is telling RAI what to keep. "Keep the brick, shutters, white trim, and roof" means the only thing that changes is what you asked to change. Same house, same angle, same light. Just the door.
You can get more specific if you want. Down to the exact paint brand, finish type, hardware style. You can even add inspiration photos from your Imagination Library. But you don't have to. "Navy blue front door" is enough.

Your house has different brick, different trim, different light. These three colors worked on this Cape Cod. Yours might want something completely different.
