What 73 tells you about Eider White
The published LRV of Sherwin-Williams Eider White SW-7014 is 73. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Eider White's cool gray description makes it a colored white choice rather than a guaranteed factory-white match.
The choice beside white cabinetry and gray porcelain
A cabinet door and porcelain tile are repeatable physical references; agreement with their exact finishes matters more than the word white.
Read the narrow edge between Eider White and the existing white from several steps away. Repeat with First Star in that same position. The question is whether the wall needs a barely visible transition or an obvious boundary; a high LRV can support either result depending on its neighbor.
What the comparison can—and cannot—settle
Eider White has an LRV of 73; Sherwin-Williams First Star SW-7646 is 69. The difference is 4 points, with Eider White returning more light under the reference measurement. Eider White is a cool white softened by gray. The value measures reflectance, so it cannot by itself identify an undertone, a coating finish or the amount of illumination needed in the room. The daylight and evening-light checks covers that related choice.
Check the factory cabinet finish before choosing this as a white-on-white scheme. Do not read LRV 73 as a percentage improvement in perceived room brightness. Make the decision with the board upright at the actual wall or cabinet position, including the least illuminated portion. The north-facing room assessment covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
