If you want a greyish tone, "lime wash" with a pale grey paint. For a brownish tone, use a very pale tan or taupe. You can add pigment to the white to tint it for the desired color.

After 4+ years, my floor has developed quite a patina. Where there’s no foot traffic more of the light color lime shows. On the highest walked area it has rubbed into the texture of the concrete. I sealed it with a soy-based sealer, EcoFlorz. I probably could have done more coats and more often, but I just clean with vinegar water or diluted Bronner’s soap. My advice when doing a patio floor would be to brush or roll it on sparingly so your grass/plants don't get hit and it doesn't splash you. You can do several layers if you wish. Outside, or for several layers on a wall, I would add an aggregate like fine sand or marble powder, as well as the salt (1/5 - 1/6 table salt to S lime). Always have vinegar nearby in case the lime solution hits your skin, and wear googles to be on the safe side. My understanding is that once lime dries it goes back to being a calcite (stone) but when it is wet it will burn; a burn you don't necessarily notice right away.

Nicktip, A good landscaper should be able to do it. You might try Maryanne White (here is an example of her work: https://www.mariakillam.com/whitegardens/ ). She also does the hardscaping -bulking up the exterior column, picking the lights, etc. She does online consulting, too. She charged $500 to design our front yard.

Paint the fence and gate black. I recently spray painted part of my mother's chain link fence and posts. It was very easy to do. Rustoleum spray paint. Give the gate a bit of a brush with a wire brush before painting. Downspouts dark brown so they don't contrast against the brick. This isn't a house for an elaborate driveway. Black asphalt will look just fine. I can't see enough of the house to see where a walkway would go so I won't comment on that. But again, nothing too patterned or colourful. I've seen too many "fancy" walkways that clash badly with the house's brick, although they probably looked great at the showroom or in a brochure. I'd stick with dark brown slabs. She can stain (not paint) the new brick to match the old brick. Stain can be custom tinted. https://romabio.com/faqs/#masonry What is the white box to the right of the driveway? Can it be painted to make it less obvious? After removing the evergreens, come back for advice on planting. For now, I'd remove the 3 sad shrubs in the middle of the grass.
