What 37 tells you about Mega Greige
The published LRV of Sherwin-Williams Mega Greige SW-7031 is 37. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Mega Greige is deeper than Anew Gray, giving a stronger neutral wall when pale greige disappears behind light furniture.
The choice beside cream upholstery and pale stone
Cream seating and pale stone can remain distinct against it, but the same depth may feel more pronounced in shaded connecting spaces.
The editorial priority for this color is a deeper greige when light neutrals disappear. Place the Mega Greige board against the actual trim, then move it to the least illuminated part of the proposed wall. Judge the visible boundary from a normal viewing distance. A value that looks suitable on a table may produce too little distinction from one fixed finish and too much from another.
What the comparison can—and cannot—settle
Mega Greige has an LRV of 37; Sherwin-Williams Anew Gray SW-7030 is 47. The difference is 10 points, with Anew Gray returning more light under the reference measurement. Mega Greige is a warm greige with medium depth. 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.
Keep it if the sofa gains definition; compare the room's shaded wall before increasing the painted area. Do not read LRV 37 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.
