What 84 tells you about Blank Canvas
The published LRV of Behr Blank Canvas DC-003 is 84. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Blank Canvas and Swiss Coffee 12 have nearly identical published screen values and equal LRV, limiting what a digital comparison can establish.
The choice beside cream cabinetry and pale oak
A physical difference beside cream cabinetry is more useful than inventing a dramatic undertone story from a one-step RGB difference.
Read the narrow edge between Blank Canvas and the existing white from several steps away. Repeat with Swiss Coffee 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
Blank Canvas and Swiss Coffee both have a published LRV of 84. That equality describes reflectance, not matching colorants or identical undertones. Blank Canvas is a high-reflectance Behr white; its published digital values are exceptionally close to Swiss Coffee 12. 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.
Do not turn a tiny screen difference into a strong undertone claim; order both authentic samples if the choice is close. Do not read LRV 84 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.
