Should You Wear White or Black on Hot Days? Here's the Data (2024)

Should you wear white or black during the summer? Or that other burning fashion question: Is it OK to wear white after Labor Day? Oh wait, that question really isn't important. Let's get back to the summer question.

There are two answers to the black vs. white clothing question.

1. Wear White. A white object is white because it reflects white light, and white light is a combination of all the visible colors. This means that a white shirt (or pants) will reflect most of the light and not get hot. Simple, right?

2. Wear Black. But wait! What about the bedouin in the desert regions of North Africa? They often wear black clothing, and it's super hot there. It seems they wouldn't wear black unless there was an advantage. Maybe the black clothing prevents body heat from reflecting back on the human—thus keeping the body cooler than a white outfit.

OK. Let's be clear. This black vs. white clothing isn't exactly a settled issue. People actually study this stuff—here is an article from Nature published in 1980: "Why do Bedouins wear black robes in hot deserts?". There are clearly several situations to consider with the Bedouin clothing. But what about more common outfits, like a T-shirt? Should you wear a black or white T-shirt on a warm summer day?

The first thing to consider: Does a black shirt get hotter than a white one? I can explore this question with an infrared camera. You see, everything gives off light (electromagnetic radiation). Some super-hot things (like a lightbulb filament or a stove burner) are hot enough that this emitted EM radiation is in the visible spectrum, and we can see it. For most other objects, the emitted light has a wavelength that puts it outside the visible range. Most of this light falls in the infrared region.

Using a special camera, a sensor detects the infrared radiation and uses this to determine the object's temperature (for the most part).

So let's do it. Here are some shirts hanging out in the sunlight.
