I have a stupid question to ask (I live in the cold, flat part of Canada, so forgive me) - if hurricane Harvey is 'gifting' you a new roof, isn't there a risk that the river rock would one day be picked up and thrown at your windows??? It's too bad the driveway likely cant be adjusted - currently you drive up, park, and cant see the front door until you walk around the garage, that's less welcoming than ideal. The back of your house looks like an oasis - lovely! The front seems to be lacking the large windows that the back has (perhaps due to privacy)? I'd suggest - paint that garage door to match the trim color, and if you can afford it, contemplate a garage door with windows to make the front look less like a 'wall' (is that a window on the right between the two stone columns?) - change the front door to one with more glass, possibly enlarging the opening to make it taller, using similar shape/muntins as the rear windows - since you have a fairly 'island/nautical' theme going on in the back with the rock+faux-dock-path, I'd suggest replacing the 90deg square path from garage to house with something more natural-form, and possibly in similar materials. I almost wonder if a post-and-heavy-saggy-rope-fence along the edge of the driveway would help carry that same feeling (and then break it to have a gap where the walking path would be)

https://www.upsidetosmartside.com/blog/fresh-color-palettes-for-a-brown-roof/ Use the Portrait Blue for the walls, and the Stone Door for an accent trim and Enchanted Cottage for the Front Door and porch post. Don't contrast the trim around the garage doors, let the walls, garage doors all be the same color.The house will look much larger.. Do make the guttering the same color as the surface behind it is. If you search "What brand of Paint is Portrait Blue" this whole assorted page of links shows up in Pinterest mentioning Behr and SW... The house will look larger with a lighter color. Grays and Blues are very close in color. WIth your brown roof, a shade of blue is the closest to gray that will match it. There are many shades of gray from confederate gray on up..Maybe this Portrait Blue would be more gray in the day light. The house could use some lighter tones probably to make it look more inviting. I hope you find a paint color you like!! Keep us posted! :)

I am a HUGE fan of Timberlane shutters in PA. The quality of these shutters is extraordinary. I have had them on my house now for 16 years - had them painted by my local painter, still look great. My DD got them about 3 years ago and they now offered the color she wanted in a factory paint job. The rep told me that these same shutters had been on the outside of their building in PA (harsh winters there!) now for 19 years and still looked great. One of the things they offer is copper guards that slip right on top of the shutter. Shutters tend to rot from water getting into the seams where the shutter dowels are held. This prevents that from happening. I think this is part of their success. Yes, they are expensive, but they will last for many decades with little if any maintenance required.

I have a "garage forward" house, and perhaps what you don't like is the strong statement the stone makes but only halfway. So it's a pretty big contrast between the stone and the other side of the garage which makes a strong out of balance statement. I'd paint the house a color closer to the stone so there's much less contrast. Painted stone is like putting tinfoil on a turd, IMHO. You could also cover the stone with siding that matches the pillar or some other siding on the house. The problem with your house now is that the garage is looking way too prominent considering how pedestrian that part is, with the entrance receding into the background. That can be fixed with paint and landscaping. But if you have your heart set on a white house . . . I dunno, maybe cover the stone with stucco. I just think painted white stone is going to look cheap. Colorful front door will be a nice update too.
