Yeah.. the pic quality isn't the greatest. That "peach" doesn't look peach at all irl. It's raffia cream by Behr and yeah it will be staying. In the last pic.. sorry, it's blurry, but you can see the living room. It is painted Harvest Brown by Behr.

Are you in an area where snow might be tracked in? If so, consider luxury vinyl plank flooring stead of laminate. Laminate will warp and buckle if drips aren’t wiped up quickly.

Mockup time! I tried to use the blue from your 'Wish list' album, but kept some warmth to go with the brick and fencing. The trim color hasn't changed much, a warm slate grey, I somewhat matched the roof with it. In real life the roofing should indeed be picked before the paint. Window frames and (garage) doors in offwhite, towards cream. No idea what material is on the steps/deck, but I muted the orange a bit. Hope you like it. (to return a favour paypal.me/rinkedit)

You're right to be concerned about how your warm toned stone and brick will look with a gray roof. The area I live was built in the early 1970's so lots of warm tones, and some of the replacement gray roofs make the whole house look really off. There's a reason your original roof is brown. What colour were your original windows?
