SW Carnelian with Aged White for trim.

My suggestion would be a warm grey (pigeon!). Bring some swatches home and pick a color from the greyest of tones from the stone. Which I wouldn't paint, btw. This nice soft color will bring out the best of the stone facade. A creamy white trim will be great...if you wanted, you could add just a touch of black or darkest charcoal (again a hint of warm). You might consider shutters (black) flanking the front window(s). I would consider replacing the roof support on the front porch with a column, creamy white. Then add a wood railing to frame it. I little corny, but top is off with a porch swing and some fresh pillows, potted flowers and color outdoor rug. Front door in either the black OR you could have a surprise with a punch of color. Picture perfect!

The gutter can be painted to match the gray roof. The eaves can be the same color as the walls (a tan from the stonework or a light greige), not dark like the roof. The main front door should be painted to draw attention. The other front door could be painted the same as the walls.

IMO adding any black paint anywhere will not coordinate well at with the color of the stone wall........in fact if the existing stone walls are to be the star of your curb appeal, I would have loved to switch out the color of the roof.

Pull all your colors from the stones: medium to light gray and creams.
