Why should avoid black colour in hot summer?

 There's a common belief that wearing black in summer makes you feel hotter because black absorbs more sunlight, thus trapping heat close to your body. However, this idea oversimplifies things. While it's true that black absorbs more light and heat, it doesn't necessarily mean you'll feel significantly hotter wearing black clothes compared to lighter colors.

In reality, what matters more for keeping cool in the summer is the material and fit of your clothing. Loose, breathable fabrics like cotton or linen are better at allowing air circulation and wicking away sweat, regardless of color. Also, wearing a hat or carrying an umbrella can provide shade and help protect you from direct sunlight, which can be more important than the color of the umbrella.

So, while black may absorb more heat than lighter colors, it's not the sole factor in determining how hot you'll feel. It's more important to choose clothing that's comfortable, breathable, and provides adequate sun protection, regardless of color.

Different colors absorb and reflect light differently. Dark colors, like black, absorb more light across the spectrum, including visible and infrared light. This absorption can lead to a slight increase in temperature if you're directly exposed to sunlight. Lighter colors, on the other hand, reflect more light, which can help keep you cooler by reducing the amount of sunlight absorbed.

Avoiding black umbrellas in hot sun is based on the same principle as avoiding black clothing: black objects absorb more sunlight and heat. When you're using a black umbrella, especially in direct sunlight, it can absorb a significant amount of heat, which could potentially transfer to you, making you feel hotter.

while black umbrellas may absorb more heat than lighter-colored ones, whether or not you should avoid using them in the hot sun depends on your personal comfort, the level of sun protection provided, and the availability of alternatives. If you find a black umbrella comfortable and effective for sun protection, there may be no need to avoid using it. However, if you're concerned about heat absorption, consider using a lighter-colored or reflective umbrella instead.
