How much hotter do you get wearing black?
According to our research, it's a myth that black clothes make you hotter. In fact, in some cases, black clothing might keep you cooler. Whether you should wear black or white in the sun has intrigued scientists enough that they've done studies with infrared cameras, bird plumage, and Arab desert clothing.
In most cases white clothes look just like black clothes in the infrared spectrum. They both reflect about the same amount of thermal radiation. That means you are going to be better off with white clothes, since they don't absorb as much visible light.
Darker colors absorb more UV than lighter colors like whites and pastels. This means the UV rays are less likely to reach your skin. But bright colors such as red can also absorb UV rays. The more vivid the color, the greater the protection—a bright yellow shirt is more protective than a pale one.
The outer layer of fabric does get hotter because the black color absorbs more heat. And that heat doesn't get transmitted to the skin because of the thick fabric. But thin black clothing transmits that heat to the skin, making a person hotter.
Choose dark and intense colors for sun protection
A study conducted in Spain found that fabrics with darker or more intense colors tended to have better UV radiation protection than lighter colors. Of all colors tested, dark blue offered the best levels of UV protection, making it the best color to wear in the sun.
The research team – C Richard Taylor and Virginia Finch of Harvard University and Amiram Shkolnik and Arieh Borut of Tel Aviv University – quickly discovered that, as you might suspect, a black robe does convey more heat inward than a white robe does.
White, silver, and other light colors are coolest, reflecting about 60 percent of sunlight but there are dark "cool" colors that can also stay cooler than traditional dark colors.
In a survey on how people perceived other people based on the colour of clothes they choose, black was seen as serious, reliable and a solid player, ideal for interviews and first dates. Of the 1,000 people surveyed, 56% of respondents favoured black as a colour of confidence – 48% of them women and 64% men.
Light colored clothing reflects most of the visible wavelengths which, in turn, absorbs less heat. On the contrary, darker or black clothing absorbs more wavelengths, absorbing more heat, hence making the clothing warmer to wear.
Color: The color of your clothing can affect how well it protects you from UV rays. Dark or bright colors, including red, black and navy blue, absorb more UV rays than lighter colors like whites and pastels. For example, an everyday white cotton T-shirt has a UPF of only about 5.
Is it OK to wear black in summer?
However, black clothes and accessories needn't be avoided in the summer months; some of the best pieces on the market—dresses, tank tops, sunnies, beach hats, and swimwear—come in elegant, polished black and effortlessly, also keep you cool.
According to the study, the most attractive color in terms of fashion is black. The second most attractive color is pink, followed by the color yellow.

White, yellow, gray, and red
It is commonly said that white is the most appropriate colour for summer temperatures because it keeps the body cool, unlike black which tends to absorb heat.
After white, the colours that keep the body cool are none other than yellow, grey, and — surprise — red, still considered in the collective imagination as a 'warm' colour. Purple is in the middle of the ranking, so it can be worn during hot weather if it is your favourite colour.
Well, as light hits a black (or bright-coloured shirt), the light is converted into energy and, in this case, heat. So, while the dark colours will absorb the light and make you a little sweatier, it will also prevent the UV rays and light from causing permanent damage.
Certain colors absorb and trap the sunlight more than others. Light-colored clothing easily reflects the sunlight, while dark clothes have trouble reflecting the sun's rays. Because of that, the dark-colored clothing traps the heat from the sun. This then makes you feel much hotter.
Protect your skin when you go out by finding articles of clothing that are deep red or dark blue for increased protection against ultraviolet rays.

White, red and yellow are best for the warm months when you want to avoid attracting extra heat. In cool months, those same colors are best traded for blue, violet or black when you want to trap as much heat as possible.
What loses heat faster white or black?
Darker materials also emit radiation more readily than light-colored materials, so they cool faster.
