I usually like a color scheme like this for brick it complimants the brick nicely. IMO you need a new front dooe I don’t think that one suits the house.just plain glass no grids would be better I would also paint the garage door the same as the siding.The shutters are actually the wrong sixe nad i would remove them for painting anyway and see if you like it better without them. A nice walkway from the road to the front door is always a nice addition tocurb appeal with some good landscaping/

i wouldn't do all four walls. maybe one wall, and the others white. find a vintage desk (or dresser or night stand) and paint it bright orange as an accessory Instead of bright orange walls, maybe do something boho w/white walls, and add peach and coral wall hangings, fairy lights, a rug, pillows, etc. or, some other ideas. show her these pics and see what she likes best. how about a Sherbet ceiling color? add some whites/golds/ soft pinks maybe an ombre accent wall? this is a nice combo. one wall coral gables, and the other three the lighter one Behr paint is cheaper than BM, and just as nice **if doing a very saturated color like orange, it's a good idea to prime the wall first (no, not paint and primer). get an actual primer and have them tint it one shade lighter than the wall color you pick. This way you won't have to do 3-4 coats of your paint color. I did a deep chili pepper paint color over a white wall once and it took so many coats. Reds, oranges, deep saturated colors should have a primer a shade or two lighter, on the wall first.

Odd that your lantern lights at the front door are not mounted at the same height. I would correct that. New ones should be 1/3 the door's height. You might consider picking a darker gray from the stone and painting the brick that color to unify the house. You should be able to find a brick that is close enough in style to replace the medallions before you paint it all one color. Check out Romabio for new high tech masonry paints and washes with less maintenance. Once the body of the house is gray, the white trim will be ideal. What are you thinking regarding landscaping? I would certainly remove those two tall bushy shrubs in front.

I like the one that @Beverly likes. Not to be snarky, but contractors aren't always the best people to choose colors for you. But if the product rep says a color looks purple when installed, THAT I would pay attention to.
