Choose by the material relationship as well as the number. Pearly White's gray undertone makes it a different proposition from whites chosen primarily for yellow or beige warmth.

The choice beside cream cabinetry and gray-veined stone
A cream cabinet and gray-veined stone create two competing references; the paint must be judged against both together.
Set up both candidates with cream cabinetry and gray-veined stone. 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 Natural Choice has an LRV of 73.
Test both fixed finishes at once; a cool gray-white may connect them or make their difference clearer. Assess Pearly White and Oyster White 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.
