Judge Felted Wool under the light you actually use, rather than expecting one constant screen appearance. Its LRV is 28; the key concern 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.

Keep the surroundings in the test

For Felted Wool, inspect the darkest painted position with the ordinary lamps alone. Then compare a better-lit part of the same board. Decide whether the low-light silhouette is desirable; buying stronger bulbs solely to reproduce a daylight photograph may change the whole atmosphere of the room.

A lighting result needs a practical decision

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 physical-sample checklist covers that related choice.

Record the condition that made Felted Wool 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.
