I've been looking at high end roofing tile websites and one of them has a color expert that made recommendations for house paint colors with their orange/brown roof tiles. Here is a link to some of the schemes they recommend that may give you some inspiration: https://www.davinciroofscapes.com/blog/exterior-color-schemes-autumn/ You can color match to Sherwin Williams brand paint.

I love your MCM home. I particularly love your front door. The garage door is okay, but I do think it would be better as a wood or (plexi) glass type garage door like one of the below insp pics. I also would go with a green gray for your exterior color of the body of your home like one of the green/grays below. If you choose to keep your garage door, then naturally it would be painted the same as your siding or one shade darker of that color. If you do paint the siding in the greens, then change the accent color of your front door to the oranges or even eggplant or some other contrasting color. ^Glass type overhead door ^Garage door that coordinates with your front door.

I like taupe with red brick and dark roof.

It would be more typically limestone and NOT concrete. You have to be very careful not to ruin it. No sandblasting. https://artradarjournal.com/2022/02/15/how-to-clean-paint-from-limestone-rock/ https://www.chicagobungalow.org/post/2019/10/16/removing-paint-from-vintage-masonry How to Remove Paint from Your Limestone or Vintage Brick Do: Use the gentlest means possible when removing paint. Use a natural bristle brush (never wire!) to apply chemicals. Conduct a sample test of a proposed cleaning method in an inconspicuous location on the building first. Use an alkaline paint remover. Examples are ammonia, potassium hydroxide, or trisodium phosphate. Organic solvent paint remover can also be used (methylene chloride). A few product suggestions: Cathedral Stone Stripper (works best in weather over 60° F) (also available at Henry Frerk Sons) ProSoCo Heavy Duty Stripper (also available at Henry Frerk Sons) Peel Away 1 Heavy Duty Paint Remover(also available at select Sherwin Williams) Let the chemical rest on the surface for the time recommended by the product manufacturer. Do a thorough, low pressure, water wash of the stone when it is time to remove the chemical treatment (see product manufacturer specifications). Take appropriate precautions to ensure that you are using the product safely. Both acidic and alkaline cleaners can be dangerous to those using them, and there are additional environmental concerns associated with the use of chemical cleaners. Be sure to follow directions and dispose of chemicals responsibly. Do NOT: Sandblast! This is extremely harmful to the stone and while it will remove paint quickly, it will also remove some of the stone itself and leave it much more susceptible to future erosion. Use metal brushes as they can damage the surface of the stone and cause it to be more vulnerable to deterioration. Use acidic cleaners—they will deteriorate the limestone, which is an acid-sensitive stone. Do any chemical cleaning or saturating of brick or limestone in the colder months. Cleaning should never be done below 40° F, and generally not below 50° F. Most chemical cleaning processes force water into the walls, which can freeze in colder temperatures causing permanent damage to brick and stone. Use any masonry (brick or limestone) sealers. They are rarely necessary for historic buildings and may cause permanent damage and discoloration of your stone.
