How Hot Are The World’s Darkest Clothes?

In this video I test how big of an effect the color of clothing has in different types of weather.

For the hummer it’s 0-60 mph in 3 seconds, not 60 😂

I have worked outside in the heat (90-105) a lot from jobs before. The biggest difference in being hot or cool is the material. It's far cooler to wear light breathable material with long sleeves to keep the sun off but allow sweat to evaporate. I started wearing t shirts but learned that things like light hooded joggers made me feel coolest. The color didn't matter.

You also have to consider, in general, the _non-linear spectral response_ of different materials and coloring agents. Some materials which are black in visible light are white in infrared, and vice-versa. That can have an extremely profound effect upon the observed affect.

The black clothes are seriously the weirdest and coolest thing I've ever seen.

I kinda want to make my own and go walking town, day and night.

It's like the deepest, darkest shadow ever walking around.

Fun fact: navy/dark blue is the best color to wear in the sun because it has the best balance of UV-absorbing qualities while not warming up as much as black. Maybe the UV aspect is one reason the Bedouins like to wear black because it helps protect them from sunburns better than wearing white!

I'll probably be proven wrong later, but TheActionLab is one of the YouTubers still with a sense of honor. I respect him for putting sponsors at the very end. an advertisement is more efficient when the viewer doesn't feel punished.

my experience (mostly outside deserts) is quite different when wearing single layer blacks feels significantly warmer, sometimes even feels hot like sunbathing even if it's cold outside when there's no wind

In the Jurassic Park novel one character asks Ian Malcolm why he would wear black clothes to a tropical island, and he answers back questioning whether they understand black body radiation. I always enjoy those little scientific asides in Crichton's books.

2:33 I love how casually you say "it's about 45 degrees" 🤣 I was thinking in Celsius and my reaction was "wow he's taking that rather well. He's in his element, unperturbed"

"The answer is that it depends, on literally everything"
My favorite answer.

"0-60 mph in 60 seconds" typical hummer

Interesting. I lived in the tropics for several years and dark was always terrible to wear. My wardrobe became all light colours. So from my experience I would say if the fabric is the same, then a lighter colour is definitely cooler when in the sun.

Excellent video. Heat transfer can be rather complex and you show this perfectly.

05:45, can go 0-60 in 60 seconds… I think those figures need an Action Labs investigation 😂

[JuliusUnique]

wouldn't it make sense in cold places to still have it black outside, but white inside, and in hot placed the other way around? I even heard of white paint used to buildings to reflect the sunlight

I have experienced a major difference in temperature when wearing different color latex gloves. Maybe it's because Latex gloves are in direct contact with my skin, that I feel the black gloves instantly heat my hand when in the sun light opposed to white gloves. Maybe that's why the difference between black and white loose clothing doesn't matter too much. Have someone put a black and white glove on your hands while not looking and walk out into the sun. Because of the skin tight contact, you'll guess which hand has the black glove.

4:57 That really looks like an edit because of the smooth, textureless black...

That black outfit would make a great Halloween costume: "Invisible Pedestrian"

Thank you for making this video. I always had questions about the black and white temperature difference.
