My gut reaction is to paint entire house but I’m not an expert. I do like a midnight blue with your color brick, brown roof, etc.

Thanks

Paint all siding the same color, all the way around the house. When sides or back are different, it looks like you got tired of painting so decided to not paint the rest of the house. I like the midnight blue Kat M posted above.

I suggest white for the vertical and an off white for the horizontal siding.

Paint the soffit the white.

Paint the front door and sidelight trim black in a satin finish. Paint the garage door in the same black, same finish as the front door.

Here are some choices for you for mixing a white and an off white. You can't go wrong with Kylie.
