The choice beside brick and pale limestone
Brick and limestone create different colored boundaries, so a white that agrees with one still needs to be checked against the other.
Set up both candidates with brick and pale limestone. 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 Dove Wing has an LRV of 77.52.
Test against both materials in the same light; a gray undertone can read differently next to each. Assess Seapearl and Gray Mist 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.
