The window trim change would be to Craftsman style. Unless you are doing the work yourself it seems a lot of expense for little difference on upstairs windows. It would, however, be extremely easy to do on your front door as you would only need to change the top board. And you could replace the side lights with solid wood inserts, or you could use textured glass that would obscure the view while still letting light in. While the limestone exterior is very light it has a yellow hue. Simply speaking the easiest way to find colors that work with the warm limestone is to choose a nearby color. That was probably why the trim is green. Since you prefer a modern look, I suggest you keep your siding light and use color only in the trim. Below are two combinations that I like. I darkened the roof color in these pictures.

My house is a similar color but with brick. Originally I had a green roof and shutters. After a hail storm I needed a new roof and went with a dark gray. I had the shutters taken down and spray painted them black. This was taken at the end of the day so lighting wasn't the greatest.

have no idea what those roof colors look like, so post a pic. Nevermind, I did the work and looked them up. this is burnt sienna. It's very varigated and is going to compete w/your driveway pattern. Weathered wood on the left. works w/your house color, clashes w/your driveway. Because of your driveway, it would be best if you got one solid color roof tile. can you do a clay tile? Do you have plans on painting the stucco in the future? Much better colors to work w/your driveway. because of that driveway color, your stucco, or at the minimum your garage doors, should have a diff color. your driveway pavers are somewhat driving the color bus. you'll have to pick roof tiles that word w/those, as well as the stucco color. I actually like this combo. Timberline Wheat, with better colors for the house.

I like weathered wood. It is a more “neutral” brown IMO and not too dark. We used weathered wood on four rental properties a few years ago and they look great still. None are Tudor style, so I can’t help you with photos. Do you have samples you can hold up next to your house? That’s the best way to see how they will look.
