I'd keep the garage door the same color as the siding, No need to contrast and draw attention to it.

I don't like to contrast the gables either, makes the house squatty looking.

an entrance door color to compliment the body of the house.

a rich wine color would be great. Ox Blood would be my first choice.

No gray. (In picture #3, the siding appears to clash bigtime with the stone wall. Perhaps it's just the lighting . . . .)

I like the oxblood suggestion for the front door, and the garage door the same as the siding. It's not a design feature you want to highlight.

Thank you yes it is the lighting, not a very good quality picture.

Garage same as siding and for front door, suggest trying to complement the stone and hopefully the roof. A terra cotta shade might work and also goes well with grey.

Thank you ! Yes, Pearl Gray. It doesn’t look blue in reality maybe in the picture. We are not planning on doing anything with the stone at the moment, but maybe in the future. So far we will pick a garage door that is the same as the siding, I like the windows. And a front door that complements the house, we will also paint the brown post by the front door. The trim is Hardie Artic white.

whatever the white trim color is on the downspout and corner trim (arctic white?) match that for now and do the garage in that.

or, match the pearl gray siding color and use that.

my concern is the yellow tones of the stone.

you can get a sample of Romabio Classico and try it on the side stone. you have 72 hours to wash it off if you don't like it.

You don't have a lot to do. wouldn't take much.

Yes, Artic white for the trim and Pearl gray for the siding. Thank you for the suggestion on the stone, we will try that as well
