What Color Is Your Mountain Safety?

Choosing the color of your mountain clothing or gear goes far beyond aesthetics. Visibility, thermal comfort, safety in case of an accident, or even how quickly a fabric dries can largely depend on the color you select. Often overlooked, it's a factor worth considering.

Black, the common mistake

Since the early 2000s, black has become the dominant color in technical apparel. However, for mountain environments, it is one of the least recommended, as it absorbs more solar radiation, which can lead to overheating in demanding conditions, and significantly reduces visibility. In situations where a rescue depends on being seen, this can make a crucial difference. It also ages more poorly and accelerates the deterioration of materials exposed to the sun.

Clothing and textiles: see and be seen

• Waterproof-breathable jacket
  Better in fluorescent orange, yellow, or light green. These colors will make you more visible in fog or approaching nightfall. In crowded areas, they instantly distinguish you.
• Tent
  For the exterior, colors like yellow, orange, or white. White also provides more light inside. The floor is best in black as it dries faster.
• Sleeping bag
  For normal conditions, dark colors dry faster. For winter or technical activities, it's better to opt for a fluorescent shade: if the bag blows away, it needs to be findable.
• Insulating pad
  Classic foam pads work well in grey or black. Self-inflating pads are better in bright colors, which are easier to locate and handle.

Other key elements…

• Backpack
  A light interior will help you see what's inside better. Some ultralight Dyneema versions achieve this with great effectiveness, albeit at a higher price.
• Sunglasses
  Brown or amber lenses are the most balanced. For fog or low visibility, yellow or orange are better. The protection category (3 or 4) is more important than the color, but the latter influences eye fatigue and how you perceive the terrain.
• Helmet
  Ideal in orange, green, or light blue. Avoid black: it concentrates heat, ages sooner, and loses properties faster, especially in ultralight models.
• Ropes
  Yellow, pistachio green, or orange for good visibility. If using two ropes, they should be clearly distinguishable. Red and yellow work well as a pair. Black, however, can make it difficult to see the end of the rope during a rappel or in low light.
