IMO the brick is what makes the house so if devaluing your home is the sim paint the brick . Please take a pic of the brick close up post it here in a commnet do not start another post. If I see the bricker closer it will help to choose color for siding and window trim. The you to work on landscaping . I would probably also show thw garge in the pics nad if you have chosen a door please also include that . IMO wait until you decide on the other color before choosing a door.

What are you willing to change? Just paint? If so a dark color like ffpalms shows for everything painted- black fox, urbane bronze... Test several to see what is best with the brick. The wood door sounds nice (plain!) and then great landscaping. The house has great lines already!

Something like an off-black or a navy on the painted siding would update things nicely and contrast/highlight the brickwork. Some low maintenance landscaping that helps frame the house and brings in color (get some evergreens too!) would probably make a big difference too. Landscaping doesn't have to be time consuming, we had a stunning front yard that only required a few hours of maintenance annually with the exception of lawn mowing.

Paint the trim & front door dark gray

Install larger coach lights at the entrance.

I would go with charcoal gray around the windows instead cream.

Brick actually goes good with charcoal.

Here is color combo I suggest. Your brick and gray.
