Begin with the weaker light
Felted Wool can be assessed for a north-facing room, but the direction alone cannot determine the result. 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
Treat a north-facing room with Felted Wool as a possible enclosed, dark scheme rather than a failed bright one. Assess the room under its normal lighting and decide whether pale furniture and architectural edges remain readable. If brightness is the main goal, compare a different depth before extending the paint.
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 situations that call for another color covers that related choice.
Window size, obstruction and season still matter when choosing Felted Wool. A compass direction is not a brightness measurement. In the Northern Hemisphere, north-facing daylight is often less directly sunlit; the actual room remains the test. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
