What 75 tells you about Heron Plume
The published LRV of Sherwin-Williams Heron Plume SW-6070 is 75. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Heron Plume's violet undertone is a reason to assess it carefully against warm fixed whites.
The choice beside ivory cabinets and gray fabric
An ivory cabinet cannot be made compatible simply by calling the wall off-white; the actual boundary needs to feel intentional.
Read the narrow edge between Heron Plume and the existing white from several steps away. Repeat with Aesthetic White 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
Heron Plume has an LRV of 75; Sherwin-Williams Aesthetic White SW-7035 is 73. The difference is 2 points, with Heron Plume returning more light under the reference measurement. Heron Plume is a cool white with a violet undertone. 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.
Test the permanent ivory first; avoid selecting this white solely because a screen image looks neutral. Do not read LRV 75 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.
