The decision for this particular color
Mega Greige can be considered for whole house if its color and depth suit the space; the first design question is a deeper greige when light neutrals disappear. Mega Greige is deeper than Anew Gray, giving a stronger neutral wall when pale greige disappears behind light furniture.
Why the cream upholstery and pale stone relationship matters
Cream seating and pale stone can remain distinct against it, but the same depth may feel more pronounced in shaded connecting spaces.
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.
Walk the connecting sightlines
Carry one Mega Greige board from the brightest room to the connecting hall and the room with the least useful daylight. Leave each room's fixed whites visible. The cream upholstery and pale stone palette may work in the main space yet fail beside a different upstairs carpet. Inspect both sides of the connecting doorway; a common paint name does not require an identical-looking wall in every exposure.
A shared palette does not require one paint everywhere
Keep it if the sofa gains definition; compare the room's shaded wall before increasing the painted area. The north-facing room assessment covers that related choice. The situations that call for another color covers that related choice.
If Mega Greige passes in the main room but fails against another fixed floor, a related color in that space may be more coherent than repeating one formula everywhere. Review both rooms through the connecting doorway. The living-room palette covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
