The choice beside oak furniture and white cotton
Oak and plain cotton can keep supporting materials simple, allowing the blue intensity itself to remain the primary choice.
Set up both candidates with oak furniture and white cotton. 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, Salty Dog is recorded at LRV 5. The undertones and neighboring colors covers that related choice.
Keep accessories quiet while comparing it to a grayer navy; the blue intensity is part of the decision. Assess Indigo Batik and Sea Serpent 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.
