The decision for this particular color
Classic Gray can be considered for living room if its color and depth suit the space; the first design question is enough contrast to justify a second neutral. Classic Gray's lightness makes subtle separation its useful role; demanding a strongly outlined gray wall would suggest a different brief.
Why the white trim and pale limestone relationship matters
Pale limestone and white trim can leave little value contrast, so the decision may be about whether a second neutral is needed at all.
The manufacturer's coordinating suggestions include Simply White OC-117, Indian River 985 and Stone Harbor 2111-50. These are separate named colors to sample, not interchangeable formulas. For the material direction considered here—white trim and pale limestone—choose which surface each candidate would occupy before deciding that the whole set belongs in the room.
Review the seating area from the doorway
Stand at the main entrance with the sofa, floor and proposed Classic Gray wall in the same view. For a scheme involving white trim and pale limestone, move the paint board behind the upholstery and then beside the largest permanent surface. A match that works only behind a cushion is not enough for the whole seating area. Keep curtains in their normal position for a second review.
Build the rest of the room around the result
Retain it for a gentle wall-to-trim difference, not a pronounced gray outline. The whole-house color assessment covers that related choice. The daylight and evening-light checks covers that related choice.
For the living room, view Classic Gray behind the main upholstery from the entrance. Restore the curtains and everyday objects before approval so the room is assessed as it will be used. The coordinating color options covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
