I might go with a slightly darker, slatier blue. Like Favorite Jeans or Aleutian.

What color is your roof? Front door? My son’s home is SW Gauntlet gray with black shutters & front door, some white trim. HOA liked the combo so much they added it to their ”approved “ color pallet. Personally, I’m not fond of blue on houses, cheapens the look, but that’s just me. I think I’ve seen too many manufactured ( aka mobile homes ) in blues. But I do love blues used elsewhere.

IMO, I don’t think a gray or blue house looks great in the shade. If you must have gray, Design Interior South’s sample of white with gray trim is very attractive.

How about a sage green - not too dark - with white trim?

I don't love grey unless you have some good contrast with the roof and trim. I would go a different route. I like the white mockup others have posted. https://www.buildersservicecompany.com/what-are-the-best-home-exterior-colors
