A mushroom neutral judged against real stone
Mushroom SW-9587 has a light-to-medium reflectance value; the name alone does not establish a precise undertone. The useful starting point for this review is travertine and undyed wool. This is a proposal for assessing the color, not a claim that it has been tested in your home. The Mushroom SW-9587 manufacturer reference supplies the color identity and published specifications.
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.
Compare the actual sample to the stone's background color before labeling it taupe, beige or gray in your scheme.
Before ordering boards, organize Mushroom and alternatives such as Shiitake with the comparison chips on paintcolorvisualizer.com. Keep the brands and codes attached to the shortlist, then compare physical samples beside travertine and undyed wool.
The deciding edge: travertine and undyed wool
Travertine and undyed wool give a material-led way to assess the authentic sample without inventing an undertone from the screen chip.
Use Mushroom and Shiitake to clarify the material choice against travertine and undyed wool. 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.
The color reference at Coloraw Mushroom SW-9587 can help organize the undertone questions for Mushroom. For this review, the practical check is the relationship with travertine and undyed wool; the digital reference does not replace that material comparison.
What Mushroom SW-9587 actually brings to the palette
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.
Use Sherwin-Williams and the complete code SW-9587 when ordering a sample. The working question is a mushroom neutral judged against real stone. A broad family name cannot settle the relationship with travertine and undyed wool.
Plan how much of the room should carry Mushroom with Paintuma Paint Color Visualizer, keeping travertine and undyed wool visible in the scene. Compare the main wall, trim and cabinet areas before buying samples, and use the physical boards to approve the color.

A palette with Mushroom in a defined role
The manufacturer's coordinating suggestions include Cheviot SW9503, Western Reserve SW9597 and Lotus Petal SW9697. These are separate named colors to sample, not interchangeable formulas. For the material direction considered here—travertine and undyed wool—choose which surface each candidate would occupy before deciding that the whole set belongs in the room.
Choose the main painted surface before assigning trim and accent colors. In the travertine and undyed wool direction, let the largest fixed surface set the constraint. Compare unequal sample areas that reflect the intended room, rather than assuming three equal paint chips describe the finished balance.
Mushroom, Shiitake or Moth Wing?
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.
Sherwin-Williams Moth Wing SW-9174 provides another reference at LRV 29. These are separate colors to compare, not promised formula matches. Keep the samples at equal size and orientation, then cover each alternative in turn so the preferred paint is also judged alone.
| Color | Brand / code | LRV |
|---|---|---|
| Mushroom | Sherwin-Williams SW-9587 | 57 |
| Shiitake | Sherwin-Williams SW-9173 | 51 |
| Moth Wing | Sherwin-Williams SW-9174 | 29 |
LRV 57: the light question for Mushroom
An LRV of 57 places Mushroom between the pale off-whites and the deeper accents considered here. On a wall, that makes separation from the adjoining finish a useful test. Compare the actual edge rather than predicting contrast from the color name or from a photograph's exposure.
Check the window wall, a shaded return and the room under its usual lamps. Keep travertine and undyed wool together as you move the sample. Record which relationship changes; a different phone exposure is not evidence that the paint will behave differently.
The final sample decision for Mushroom
Compare the actual sample to the stone's background color before labeling it taupe, beige or gray in your scheme.
Label the board Sherwin-Williams Mushroom SW-9587, apply and dry it according to the product directions, and approve it in the intended finish. Keep the failed condition in your notes as well as the successful view. Color choice does not specify cabinet preparation, bathroom suitability or an exterior coating system. The paint color visualizer roundup compares tools for planning the painted areas before the physical trial.
