The choice beside cream fabric and weathered wood
Weathered wood and cream fabrics provide a restrained support palette, but a narrow hallway may need a separate depth decision.
Set up both candidates with cream fabric and weathered wood. Use equal-sized boards with the intended finishes and place them in the same orientation. Do not put one directly beside a window and leave the other in shadow. A difference that follows the position rather than the board is a lighting observation, not evidence that the formula changed.
What the comparison can—and cannot—settle
The alternative Contented has an LRV of 52. The undertones and neighboring colors covers that related choice.
Keep the added depth if it anchors the furniture; check a lighter green before using it through a narrow hall. Assess Coastal Plain and Rain alone as well as side by side. The unchosen board will not remain in the finished room, and a preference created only by that neighbor may not survive its removal. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
