Black vs White vs Green Shade Cloth
Color matters more than most growers realize. Here's a practical comparison to help you choose the right shade cloth color for your application — whether it's vegetables, orchids, greenhouses, or outdoor structures.
When shoppers search for shade cloth, they often filter first by percentage — but color is equally important. Black, white, and green shade cloth have meaningfully different effects on heat reflection, light spectrum, ambient temperature, and plant response. This guide breaks down the important differences so you can make the right call for your situation.
All of Pro Fabric Supply's knitted shade cloth is made from 100% UV-stabilized polyethylene with lock stitch construction, so it will not unravel when cut. It is available from 30% through 90% shade, and every percentage comes finished (edges fully taped with grommets every two feet) or unfinished (no tape or grommets). Colour availability varies by percentage, so check the option you need before ordering.
Quick Comparison: Black vs White vs Green
Black Shade Cloth — The All-Purpose Standard
Black Shade Cloth
Black is the default choice for most applications, and for good reason. Beyond the UV stabilisation built into every knitted shade cloth, the carbon-black pigment itself absorbs UV radiation, which is part of why black shade cloth holds up so well outdoors.
- Best for: vegetables, orchid houses, general agriculture, animal shade
- Absorbs heat at the fabric level but still substantially reduces the temperature below
- Excellent light diffusion creates even canopy coverage
- The most widely available colour across the full percentage range
White Shade Cloth — Superior Heat Reflection
White Shade Cloth
White shade cloth reflects solar radiation rather than absorbing it. Because the fabric itself stays cooler, less heat radiates downward from the cloth — which is why growers in hot climates and greenhouse operators often prefer it over black at the same shade percentage.
- Best for: greenhouses, seedling propagation, heat-sensitive crops in extreme climates
- Reflects rather than absorbs, cooling the cloth itself and not just the shadow below
- Transmits slightly more light at an equivalent percentage, so the space reads brighter
- A common choice for commercial greenhouse operators in hot regions
Green Shade Cloth — Natural Look, Similar Performance
Green Shade Cloth
Green shade cloth performs much like black on most practical measures, while its tint transmits a little more of the green part of the spectrum. For most garden and nursery use that difference is negligible. The main draw is appearance — green blends into planted surroundings instead of standing out.
- Best for: residential gardens, nurseries, decorative shade structures
- Blends with natural surroundings and looks less industrial than black
- Sits between black and white on heat reflection
- Preferred by some flower growers for its slightly different spectral output
What About Aluminet? Reflective Shade Cloth Explained
Aluminet is aluminized reflective shade cloth — a metallized fabric that reflects solar radiation more effectively than any pigmented colour option. It is a premium product used in professional greenhouses and high-value crop production. Key characteristics:
- Reflects a large share of incoming solar radiation rather than absorbing or simply diffusing it
- Can cut greenhouse temperatures substantially compared with unshaded conditions
- Doubles as a thermal screen at night, reducing heat loss
- Costs considerably more than standard knitted shade cloth
- Most practical for permanent greenhouse installations with track systems
Aluminet is not part of the Pro Fabric Supply range. For most home gardeners and small-scale growers, white or black UV-stabilized knitted shade cloth delivers strong performance at a fraction of the cost.
Colour and Heat Reflection: The Practical Picture
The albedo (reflectivity) of a shade cloth colour matters most when the fabric sits in direct sun for long stretches. A black cloth in full sun becomes far hotter to the touch than white — but both cast a shadow that cuts the radiation reaching plants. What that means in practice:
- In very hot climates, white shade cloth offers a worthwhile additional cooling benefit over black
- In moderate climates, black performs nearly as well as white for plant protection
- Where the cloth sits low and radiates heat downward — a low greenhouse roof, for instance — white meaningfully reduces that radiated load
- Shade percentage is still the bigger lever than colour: moving from 30% to 50% changes conditions more than switching colour at a fixed percentage

| If you are... | Choose |
|---|---|
| Growing vegetables in a hot climate | White at a lower percentage (30–40%) for maximum heat reduction |
| Covering a greenhouse in summer | White at 30–50% |
| Shading orchids outdoors | Black at 50–70% for excellent diffusion |
| Protecting a patio or pergola | Black or green — both sit better with furniture and structures |
| Shading animals or livestock | Black at a higher percentage for durability and deep shade |
| Nursery or garden aesthetic use | Green, which blends naturally |
| Screening a fence line for privacy | Black or green at 80–90% |
| General-purpose, or not sure | Black — the most versatile and widely stocked |
Frequently Asked Questions
Which color shade cloth is best for vegetables?
Black is the most popular and versatile choice for vegetables — it provides even light diffusion and, like all of Pro Fabric Supply's knitted shade cloth, is made from 100% UV-stabilized polyethylene for multi-season durability. In climates with sustained extreme heat, white shade cloth reflects rather than absorbs solar radiation and may suit heat-sensitive crops better.
Does white shade cloth reflect more heat than black?
Yes. White shade cloth reflects solar radiation rather than absorbing it, so the fabric itself runs cooler and less heat radiates down from it. That makes white a common choice for greenhouse applications and extreme-heat environments. Both colors reduce the temperature below the cloth compared with no shade at all.
What is aluminet shade cloth?
Aluminet is a reflective, aluminized shade cloth used in professional greenhouses and high-value growing environments. It reflects solar radiation more effectively than a pigmented fabric of the same shade percentage and can also act as a thermal screen at night. It costs considerably more than standard knitted shade cloth and is not part of the Pro Fabric Supply range.
Is green shade cloth better than black?
Not inherently better — just different. Green performs similarly to black on most practical measures but blends more naturally into garden and nursery settings. Some growers prefer it for flower production. For most applications the performance difference is negligible, so choose on appearance and availability at the percentage you need.
What color shade cloth is best for a greenhouse?
White is generally preferred for greenhouses because it reflects heat rather than absorbing it, which keeps the fabric and the air beneath it cooler. Black can work well in cooler climates or where heat build-up is not the limiting factor. Pro Fabric Supply carries white knitted shade cloth at 50%, which suits many greenhouse and propagation setups.
