Give this sample a clear job
Sample Benjamin Moore Classic Gray OC-23 beside the fixed finishes, in the intended orientation and under normal room lighting. The trial should settle 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.
Classic Gray has an LRV of 73.67; Benjamin Moore Pale Oak OC-20 is 68.64. The difference is 5.03 points, with Classic Gray returning more light under the reference measurement.
Keep the comparison fair
Use Classic Gray and Pale Oak to clarify the sampling choice against white trim and pale limestone. Keep the sample edges touching the fixed material, and cover one color before judging the other. Near-neutrals can look noticeably different side by side; the final choice still needs to work on its own. Record the specific relationship you prefer, such as a clearer trim outline or a quieter connection to the floor.
Approve the actual coating and the least favorable view
Retain it for a gentle wall-to-trim difference, not a pronounced gray outline. The undertones and neighboring colors covers that related choice.
Keep the approved dried board with the complete Benjamin Moore OC-23 product and finish specification. Follow the actual coating instructions for application, drying and preparation; the color name does not settle those requirements. The daylight and evening-light checks covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
