It would be too much white for my tastes. I would want some definition between the roof and the walls. I think you can achieve a clean, classic look without going white on white.

Start with the end in mind. What do you want your house to look like when it is complete? What colors are ideal for you for the siding and roof? Choose the roof color based on the overall look you want in the future. It looks like decisions are being made in an isolated thought pattern. Every thing is close to the house: landscaping in narrow band close to house with steps turned sideways; Small porch for entry only; white roof simply to make your home look "different." Think about the space as a whole and create a "tackle it as you can afford It plan" ... I bought a single story home with a white metal roof located in the Northwest. Really difficult to work with a white roof outside of a beachy environment or a two story old farm house look. The house becomes an object separate from the surrounding landscape and looks isolated. A medium color tone in the roof will better tie into the natural wood elements. A larger porch will help balance the windows and create a place to be rather than just pass through. Larger windows would be lovely in the future but adding vertical elements to complement the vertical porch posts would help tie in the front facade with the porch. Play with the idea of longer shutters or wide vertical trim boards with a change in siding under the windows to create a stronger vertical element and some textural interest. Keep the change in siding the same color as horizontal siding so the look does not become spotty. Use some vertical elements in the landscape . The taller landscape elements should not block view and light at the windows so plan the landscaping to utilize blank wall spaces and by all means pull the landscape out from the house to "marry" the house with its surroundings. The comment about masonry post bases being out of proportion is valid. Simplify. Your house has a ranch look ... IMO using natural wood elements is very ranch like and not a craftsman look only so your future finished look should carry that post and beam work elsewhere in your design. For now ... a larger front porch will be money best spent!

rocketjcat, it came from this link but doesn't look like they give the paint brands or colors. https://www.bhg.com/home-improvement/exteriors/curb-appeal/exterior-color-combinations/

For anyone curious, here she is with one coat of SW Creamy. Please ignore the mess of ladders and scaffolding and weeds-- I am not currently living in the house, so things get a bit messy in between my visits. I alternate between really liking it and not liking it, but I’m not sure if it’s just because I’ve never seen this house not be white white and so my mind is playing tricks on me because it is no longer the white my brain expects. (this is with basically full sun-- I happen to like the color in this photo) (again in sun) I am holding off on doing a second coat until I decide whether I’m happy enough with the color. For some reason now I’m feeling like I should have gone with either a darker tan/greige with cream trim...ugh I was so sure I wanted an ivory color, but it just looks so different between sun and shade. I’m a pretty indecisive person, so I knew this was going to happen. Does anyone have a suggestion for front door color? When I thought I was going to love this body color (and maybe I do, I'm just not sure yet because of the sun vs shade issue), I was considering a front door color somewhere on the spectrum between dusty pink and aged- brick red because I thought it would look nice with the cream and the green roof. It's a little out of my comfort zone-- I'm more of a traditionalist (like the typical New England white house with dark green shutters and matching door), but I thought it might be complimentary. I don't really know enough about colors to be confident in that, however. The front door is technically the door under the porch; would I also paint the door to the mudroom bump out to match? getting confused by too many options....
