The choice beside linen upholstery and medium walnut
Medium walnut and plain linen supply enough structure that nautical patterns are optional rather than necessary to explain the wall color.
Set up both candidates with linen upholstery and medium walnut. 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
For a second point of reference, Mount Saint Anne is recorded at LRV 41.9.
Let the wood and plain fabric establish the scheme before adding patterned blue accessories. Assess Santorini Blue and Boothbay Gray 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.
