The decision for this particular color
Felted Wool can be considered for bathroom if its color and depth suit the space; the first design question is a wool-like gray with green kept in the decision. Felted Wool adds green to a warm gray with more depth than Acier, making a darker colored-neutral comparison worthwhile.
Why the oatmeal fabric and walnut relationship matters
Oatmeal fabric can soften the scheme while walnut adds weight; the wall should preserve a distinction between those large material areas.
Felted Wool has an LRV of 28; Sherwin-Williams Acier SW-9170 is 32. The difference is 4 points, with Acier returning more light under the reference measurement.
Let tile and porcelain set the limits
Assess Felted Wool on the vanity or wall under the bathroom's actual lighting. Check the shadow below the countertop and the dark outline in the mirror. The porcelain can provide a large light contrast, but its brightness does not establish how the rest of the painted surface will read.
Separate the palette from the moisture specification
Set a less green gray beside it, then choose the sample that joins the fabric and wood most convincingly. The undertones and neighboring colors covers that related choice. The daylight and evening-light checks covers that related choice.
Choose a Sherwin-Williams coating appropriate to the bathroom surface and follow the manufacturer's preparation and application guidance. Color SW-9171 does not identify a moisture-control system. Ventilation, substrate condition and the intended finish are separate decisions; approve the color under the real vanity lighting before ordering the full paint quantity. The trim color comparison covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
