Start with the documented color character
Limewash SW-9589 is a warm neutral paint color; the name does not specify a mineral limewash finish. A physical comparison is needed to decide how that character works with your own finishes. Limewash SW-9589 specifies a color; selecting it does not determine mineral composition, translucency or a textured decorative application.
Why the plaster texture and natural oak relationship matters
Plaster texture can change the surface's appearance independently of the color, so approve a finish sample as well as a paint chip.
Limewash has an LRV of 67; Sherwin-Williams Taupe Of The Morning SW-9590 is 65. The difference is 2 points, with Limewash returning more light under the reference measurement. Taupe of the Morning is a softly warm neutral with relatively light reflectance. This supplies a named color control; the LRV gap alone does not identify the warmer, greener or pinker paint.
Use Taupe Of The Morning as a control
Use Limewash and Taupe Of The Morning to clarify the undertone choice against plaster texture and natural oak. Keep the sample edges touching the fixed material, and cover one color before judging the other. Near-neutrals can look noticeably different side by side; the final choice still needs to work on its own. Record the specific relationship you prefer, such as a clearer trim outline or a quieter connection to the floor.
Separate a persistent cast from a comparison effect
Choose the coating and application method separately; a standard paint tinted to this code does not automatically create a limewashed surface. The warm-versus-cool comparison covers that related choice.
If the unwanted cast remains beside a permanent finish under normal light, that is a practical reason to replace Limewash. If it appears only beside an unused sample, remove the comparison and assess the intended palette alone. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
