Follow the room through its ordinary day
Judge Mushroom under the light you actually use, rather than expecting one constant screen appearance. Its LRV is 57; the key concern is a mushroom neutral judged against real stone . Mushroom SW-9587 is much lighter than Moth Wing, though its name alone cannot settle whether a room will read it as beige or taupe.
Travertine and undyed wool give a material-led way to assess the authentic sample without inventing an undertone from the screen chip.
Keep the surroundings in the test
Begin with Mushroom beside travertine and undyed wool in indirect daylight. Check again at the time direct sun enters, if it does, and finally with only the evening lamps. Record which relationship changes: the trim edge, the floor connection or the paint's apparent hue. Automatic phone exposure can hide a meaningful difference, so make the final observation in the room.
Mushroom has an LRV of 57; Sherwin-Williams Shiitake SW-9173 is 51. The difference is 6 points, with Mushroom returning more light under the reference measurement.
The condition for keeping Mushroom
Compare the actual sample to the stone's background color before labeling it taupe, beige or gray in your scheme. The physical-sample checklist covers that related choice.
Record the condition that made Mushroom least convincing as well as its best view. If only a short period of daylight works, change the color or the room plan rather than ignoring the hours when the space is occupied. The north-facing room assessment covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
