I would find the bedspread or other fabrics first and choose a paint color from there. It will all work better for you in the long run. Much easier to find paint to match the fabric than fabric to match the paint. I would paint the walls (including the slanted ones) all the same color, to lessen the feeling of the angles in the room. Unless the ceiling is very high, I think you will be surprised at how quickly the painting will go - so once you are up there with all the equipment and before you have to move around things as the space is decorated, just do all the walls now.

Thank you for the input PPF. I love the gable over the windows to the left in your rendering. It definitely ties that part of the house in to the dormer. I know the windows aren’t aligned in the original but my architect was more concerned with centering them on the interior walls than the outside. I’ll post the floor plan to show the dilemma there. The plan only shows 2 windows on the lower left but we changed it to 3 for the elevation. Moving the lower right window isn’t an option with the wall to the laundry where it is now. I could shift the picture window and the bank of 3 windows over but that would affect the dining and living room symmetry from the inside so I’m unsure. I did a very crude mockup with stone around the front door and agree that it’s not a good look. Leaning toward using the same color siding but with a cedar shingle style on the dormer and plank on the rest for a little variety.

you pic is rather small and too far back to see the tones in the stone. here are some diff shades of neutral beige/creams if you want it to match w/the stone, then just pull one of those colors. matching the stone color is simple and safe. I do like this trio. maybe the darker green/gray for the trim or accent somewhere if you want contrast, try a warmer charcoal tone (not a blue gray,,has to be a yellow undertone charcoal. like this Anonymous shade. (bottom right) or, maybe either of these bronze colors would look nice. why not get a few samples, paint a swatch, and see what you like. some other neutrals to go w/the stone. download the SW ColorSnap app, upload your picture, and try out the diff colors to see what you like

If the gray/green on the house I posted appeals to you, these from BM could be similar. The color used on the house was a custom mix. Your brick with some black and white is very classic and nice. ETA - Just wanted to say I believe the roof color on the house Patricia and I posted is gray. Looks great with the paint color.
