anchor color 9 of 10 in Soft Autumn. Also called Muted Autumn in other systems.

Warm mushroom is the Soft Autumn mid-neutral: a soft grey-brown with warmth in it. It is two points from the season's warm taupe and three from its mushroom grey, so the three are one family for shopping. It is the color to buy when a Soft Autumn wants grey and should not have it.
Warm mushroom is an anchor color in Soft Autumn. Its closest relative outside the palette is Warm grey #A79E92, a Bright Spring color, at a perceptual distance of 7. That is near enough for that season to wear it as a neutral, with the accents kept in its own palette.
At RGB 162, 145, 126 the red leads, the green is close behind and the blue is lower, with small gaps between all three. The small gaps make it a neutral. The order, red then green then blue, gives the warm cast. It is the color of the underside of a mushroom cap. Remove the warmth and it becomes True Summer's grey-taupe; lighten it and it becomes the warm greys of the Springs.
A Soft Autumn wears it wherever another season would wear grey: tailoring, knitwear, coats, trousers. It is quiet enough to disappear and warm enough not to drain the skin. It works with oyster and soft chocolate, and it sits under sage green, dusty terracotta and warm dusty rose.
Retail calls it mushroom, portabella, taupe, cappuccino, dune and woodsmoke. Boden's Cappuccino, Marine Layer's Portabella and Woodsmoke and STAUD's Dune have landed on it. It is a staple and in stores all year. The version to avoid is the cool grey sold as mushroom, which reads pink or blue against white.
Soft Autumn's own warm taupe is two points away and its mushroom grey three; nobody can separate them on a rail. Bright Spring's warm grey is seven points off and True Summer's grey-taupe nine, both a little cooler and close enough to pass. Soft Summer's dove taupe and Light Spring's light warm grey are about twelve points away and lighter. A neutral this soft crosses seasons easily, so the check is the cast against white: sandy is right, pink is a Summer's.

Retailers almost never use the palette name. These are the color names on the in-stock pieces that sample within a close match of #A2917E today, so they are the words to search for.
A retailer's name for a color says nothing about its undertone. "Navy" at one shop is a True Winter color and at another a Spring one. The sampled dot on each card above is what we trust.
Yes. Warm mushroom (#A2917E) is an anchor color in the Soft Autumn palette, and close enough to a Bright Spring color for that season to wear it as a neutral.
For shopping, yes. They are two points apart. Warm taupe is a touch lighter and sandier. Soft Autumn's mushroom grey is three points off. Treat the three as one neutral family.
Cool grey, not well. It drains warm, soft coloring. Warm mushroom is the substitute: it does everything grey does in an outfit and keeps the warmth in the face. Charcoal is replaced by soft chocolate in the same way.
For a Soft Autumn: oyster, buttermilk, soft chocolate, sage green, dusty terracotta, warm dusty rose and muted teal. It is a base and goes under everything in the palette. Avoid black, which makes it look flat.
Close. True Summer's grey-taupe is nine points away and cooler. On a True Summer warm mushroom reads slightly sandy. It works in trousers or a coat; near the face her own grey-taupe is the better choice.
