What 42.8 tells you about French Toile
The published LRV of Benjamin Moore French Toile CSP-595 is 42.8. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. French Toile's fabric-inspired description provides a design association, not a specification that guarantees a particular undertone in every room.
The choice beside cream linen and a faded patterned rug
A faded rug contains several colors and values, so matching one blue detail should not override the palette of the rug as a whole.
Compare French Toile and Boothbay Gray at equal size, first considering depth and then hue. A lighter blue, green or pink is still a colored surface. Use the LRV to organize the depth question without assuming that it measures saturation or predicts which hue the room will favor.
What the comparison can—and cannot—settle
French Toile has an LRV of 42.8; Benjamin Moore Boothbay Gray HC-165 is 43.26. The difference is 0.46 points, with Boothbay Gray returning more light under the reference measurement. French Toile is a blue in Benjamin Moore's Color Stories collection; its fabric-inspired description does not specify a universal 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.
Compare the paint to the rug's blue area without assuming that the color name guarantees a historic fabric match. Do not read LRV 42.8 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.
