The color of mushroom in shoes can vary quite a bit depending on the type of mushroom leather used and how it is dyed or finished. Generally speaking, mushroom leather tends to be light tan or brown in color. Here is a quick overview of some common mushroom leather shoe colors:
Mushroom
The natural undyed color of mushroom leather is a light beige or tan mushroom shade. This can range from a pale almost white tan to a darker brown mushroom tan depending on the type of mushroom used and how it was tanned or processed. Mushroom is a popular choice for oxfords, derbys, loafers, and other classic shoe styles where you want to showcase the natural nubuck texture and subtle coloration of the leather.
Brown
Brown is probably the most common color for mushroom leather shoes. Mushroom leather takes dye very well, so it can be stained in various shades of brown from a soft light tan to deep chocolate brown. Brown mushroom leather has an attractive natural look while being a bit more versatile than the plain mushroom tan shade.
Burgundy
Burgundy or oxblood mushroom leather provides a rich reddish-brown color that works well for brogues, boots, or more casual styles. The depth of the burgundy color helps highlight the natural grain and texture of the mushroom leather.
Black
Fully black mushroom leather is less common but provides a more formal look. The black dye gives a deep, saturated color that contrasts nicely with the visible mushroom grain and nubuck surface texture.
White
White mushroom leather is produced by heavily buffing and processing the leather to remove the natural tan pigment. This provides a preppy, summery look for shoes like sneakers, boat shoes, and loafers.
Other Colors
Pretty much any color can be achieved with mushroom leather through different dyes and finishing processes. Some other examples include:
- Gray
- Navy
- Olive
- Cordovan
- Blue
The texture and grain of the leather will still be visible even when dyed bright colors. Exotic colors like blue or green may use a base dye with a clear top coat to allow the mushroom nubuck to show through tinted.
Multi-Color
Some mushroom leather shoes combine different dye colors on different parts of the shoe to create a multi-color effect. Examples include:
- Brown upper with tan mushroom laces and sole
- Black and white two-tone Oxfords
- Burgundy and navy blue split-color Derbys
This allows for more customization and visual interest by mixing and matching mushroom leather shades.
Distressed and Antiqued Finishes
Mushroom leather can also be artificially distressed or antiqued to create a worn-in vintage look. Examples include:
- Lightly sanded or buffed areas to reveal lighter tan undertones
- Sponged on stains and dyes to create a mottled effect
- Applied waxes and oils to darken the midtones
This takes advantage of the nubuck surface and natural variances in the leather to add character and an authentic old look.
Patina Over Time
As a natural material, mushroom leather will develop its own patina and color changes over time with wear. The natural oils in the leather come to the surface to create attractive highlighting and toning effects. Areas like toe caps and heels that see a lot of abrasion will lighten and take on a burnished appearance. Some enthusiasts even speed up this aging process manually through repeated brushing and polishing.
Conclusion
While undyed mushroom leather is a light tan color, shoe designers take advantage of various dyes, finishes, and processing techniques to produce mushroom shoes in a rainbow of different colors. The naturally variable texture of the leather takes the dyes well and adds visual interest to even solid colors. Multi-color combinations provide even more customization options. And the natural patina forming over time from wear gives mushroom leather shoes their own unique personality and vintage appeal.

Mushroom leather is a unique material made from an actual mushroom cap rather than animal hide. It has a distinctive porous and fibrous texture similar to suede. The natural color is a very light mushroom tan beige color. To create mushroom leather shoes in different colors, the leather is dyed, stained, or buffed. Common mushroom shoe colors include various shades of brown, burgundy, black, white, gray, navy, and more. Multi-color effects can be achieved by dyeing different parts of the shoes different colors. The natural texture of the leather gives visual interest and depth to the colors. Mushroom leather also develops a natural patina and aging over time with wear. This wide range of color options and character from real mushroom material makes mushroom leather an intriguing choice for fashionable and sustainable shoes.
Mushroom leather dates back to the mid 1990s when it was first developed as a potential animal-free alternative to traditional leather. It is made from the inner membrane of mushroom caps, which is extracted through a process that does not harm the mushrooms. The P. ostreatus or oyster mushroom is most commonly used since it provides a large smooth cap. Mushroom leather is breathable and absorbs dyes and finishes in a similar way to animal leather, while offering a more sustainable option.
There are a few different methods used to convert the mushroom membrane into a flexible and durable leather-like material:
- Using heat and pressure to compact and bond the natural fungal fibers together into sheets.
- Treating the membranes with chlorine to remove bacteria and increase porosity before compacting into leather.
- Coating the membranes with natural rubber lattices which act as an adhesive holding the fibers together when dried into sheets.
The finished mushroom leather has some key advantages over animal leather:
- Completely animal-free and vegan.
- Produced using sustainable mushroom farming practices.
- Biodegradable and compostable at end of life.
- Lower environmental impact than animal agriculture and tanning.
The main limitations are that mushroom leather tends to be thinner and less sturdy than some animal leathers. But ongoing improvements in processing and mushroom breeds are helping to close the performance gap. Mushroom leather is now being used by major footwear brands such as Adidas, and is becoming more popular due to rising ethical and environmental concerns around conventional leather.
Characteristics of Mushroom Leather
Mushroom leather made from fungal mycelium has some unique properties and characteristics:
- Appearance – Fibrous porous surface resembling suede or fine nubuck. Shows natural variations similar to animal leather grain.
- Texture – Soft and supple, sometimes with a subtle sparkle from embedded fungal particles catching the light.
- Thickness – Typically 1mm to 2mm thick. Thinner than most animal leathers.
- Strength – Tensile strength around 5 to 15 MPa. Not as strong as animal leather but can be bolstered with coatings.
- Flexibility – Extensible and flexible, can be crumpled and stretched without damage.
- Breathability – Highly vapor permeable and breathable due to porous structure.
- Water resistance – Absorbs moisture readily, so needs to be treated to repel water.
- Care – Can be gently hand-washed or dry cleaned. Avoid high temperatures.
With finishing processes like dyeing, distressing, and protective coatings, mushroom leather takes on properties that mimic animal leather for use in shoes and other products. But it retains a distinctive appearance and feel that sets it apart as a unique material.
Dyeing and Finishing Mushroom Leather
One of the key steps in using mushroom leather for shoes is applying dyes and finishes to alter the color and improve durability:
- Dyeing – Mushroom leather readily absorbs fabric dyes to stain it in a wide range of colors.
- Waxing – Waxes can be absorbed to make the leather more water resistant.
- Oiling – Oils enhance suppleness, color depth, and increase water repellency.
- Sealing – Polyurethane or other topcoats can be applied to seal in color and strengthen the material.
- Embossing – Textured plates or rollers can stamp interesting grain patterns.
- Buffing/Sanding – Light scuffing creates a faded vintage appearance.
A combination of approaches are used depending on the desired look and performance. The porous nature of mushroom leather allows it to absorb these treatments readily compared to animal leather. But care must be taken to avoid oversaturation or damage from harsh chemicals. With the right formulations and techniques, mushroom leather can achieve enhanced aesthetics, durability, and water resistance while retaining its sustainability benefits.
How Mushroom Leather Is Made
Producing mushroom leather for use in footwear involves the following general steps:
- Mushroom spawn is used to culture mycelium on an agricultural waste material such as straw, hulls, or sawdust in a controlled indoor environment.
- When fully colonized, the mycelium-coated substrate is heat treated to stop further growth.
- The outer skin or fruiting body of the mushrooms is then harvested and processed to extract the interior membrane layer.
- The membranes are washed, sliced, and treated to remove bacteria.
- Next the membranes are layered and compressed under heat to form a consolidated leather-like sheet.
- The sheets are finished by dyeing, waxing, or applying protective coatings and other effects.
- Finally, the finished mushroom leather is cut, stitched, and assembled into shoes and other products.
It is an intensive biotechnological process requiring extensive research and development to turn the fungal mycelium into a flexible, durable and appealing leather substitute. But the result is a 100% natural animal-free material with sustainable credentials that traditional leather cannot match.
