Marshmallow and White Heron: the documented difference
Marshmallow has an LRV of 82; Sherwin-Williams White Heron SW-7627 is 76. The difference is 6 points, with Marshmallow returning more light under the reference measurement. Choose by the material relationship as well as the number. Marshmallow's pink undertone gives the white a specific relationship to investigate beside pink-beige stone. White Heron SW-7627 is a cool white with violet undertones; it is not Benjamin Moore's same-name color.

The choice beside pink-beige marble and oak
Marble veining can be flattering while the slab background disagrees, so the entire stone sample should remain visible.
Set up both candidates with pink-beige marble and oak. 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 Ivory Lace has an LRV of 79.
Use the marble's plain background as well as its veining in the test; pink should connect rather than dominate. Assess Marshmallow and White Heron 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.
