At Wise Design our next favorite neutral paint color after a clean & bright white wall, is a calming, soothing grey wall. Grey is a paint color we return to time and time again, when we want a bit of contrast with the trim color, particularly in historic homes.
We have a few shades of grey that we return to over & over again, because they're versatile with just the right undertones. Besides these go-to greys, we have a few that we love and have yet to use on a project, but intend to in the future. (Aka our would-be-go-to greys).
